Changed to empty string (<code>""</code>) in v2.11, as the <code>"tablesorter-headerAsc"</code> class will always be added to a header cell with an ascending sort; this option now contains any additional class names to add.
Default changed v2.5 to <code>"tablesorter-headerAsc"</code>. Default changed v2.1.7 to <code>"tablesorter-headerSortUp"</code>. Original default: <code>"headerSortUp"</code></div>
<td>Add this css class to a child row that should always be attached to its parent. Click on the "cssChildRow" link to toggle the view on the attached child row. Previous default was <code>"expand-child"</code> (Modified v2.4).</td>
Changed to empty string in v2.11, as the <code>"tablesorter-headerDesc"</code> class will always be added to a header cell with a descending sort; this option now contains any additional class names to add.
Default changed v2.5 to <code>"tablesorter-headerDesc"</code>. Default changed v2.1.7 to <code>"tablesorter-headerSortDown"</code>. Original default: <code>"headerSortDown"</code></div>
Changed to empty string in v2.11, as the <code>"tablesorter-header"</code> class will always be added to the table headers; this option now contains any additional class names to add.
Changed to empty string in v2.11, as the <code>"tablesorter-headerRow"</code> class will always be added to a table header row; this option now contains any additional class names to add.<br>
<p>This CSS style was added in v2.4, prior to that the row would get the same class as the header cells. This class was added to make it easier to determine what element was being targeted in the plugin.</p>
As of v2.7, the icon will only be added to the header if <strong>both</strong> the <code>cssIcon</code> option is set AND the <ahref="#headertemplate"><code>headerTemplate</code></a> option includes the icon tag (<code>{icon}</code>).<br>
<br>
In v2.4, an <code><i></code> element, with this class name, is automatically appended to the header cells. To prevent the plugin from adding an <code><i></code> element to the headers, set the <code>cssIcon</code> option to an empty string.<br>
<td>The CSS style added to the header cell icon when the column has an ascending sort (<spanclass="version">v2.18.3</span>).
<divclass="collapsible"><br>
This class is only applied when the <ahref="#headertemplate"><code>headerTemplate</code></a> option includes a <code>{icon}</code> tag or an HTML element with the class name from the <ahref="#cssicon"><code>cssIcon</code></a> option.

<divclass="collapsible"><br>
This class is only applied when the <ahref="#headertemplate"><code>headerTemplate</code></a> option includes a <code>{icon}</code> tag or an HTML element with the class name from the <ahref="#cssicon"><code>cssIcon</code></a> option.
<td>The CSS style used to style the header cell icon when the column does not have a sort applied (<spanclass="version">v2.18.3</span>)
<divclass="collapsible"><br>
This class is only applied when the <ahref="#headertemplate"><code>headerTemplate</code></a> option includes a <code>{icon}</code> tag or an HTML element with the class name from the <ahref="#cssicon"><code>cssIcon</code></a> option.
<td>Additional CSS class applied to style the header when no sort is applied (<spanclass="version">v2.15</span>).
<divclass="collapsible"><br>
A <code>"tablesorter-headerUnSorted"</code> class will always be added to an unsorted header cell; this option contains any additional class names to add. Currently, no themes use this class name.
Changed to empty string in v2.11, as the <code>"tablesorter-processing"</code> class will always be added to a table cells during processing; this option now contains any additional class names to add.<br>
<p>This class name is added to the header cell that is currently being sorted or filted. To prevent this class name from being added, set the <ahref="#showprocessing"><code>showProcessing</code></a> option to <code>false</code>.</p>
As an example, I've split up this options table into three (3) tbodies. The first contains the active options, the second is the info block with a row that only contains the text "Deprecated Options", and the last tbody contains the deprecated options. Sort the table to see how each tbody sorts separately.
<spanclass="label label-info">NOTE!</span> The pager plugin will only be applied to the first tbody, as always. I may work on modifying this behavior in the future, if I can figure out the best implementation.
<td>Class name added to element inside header. Clicking on that element, or any elements within it won't cause a sort. (<spanclass="version">v2.20.0</span>).</td>
In previous versions, this option was set as "us", "uk" or "dd/mm/yy". This option was modified to better fit needed date formats. It will only work with four digit years!<br>
The sorter should be set to "shortDate" and the date format can be set in the "dateFormat" option or set for a specific columns within the "headers" option.
Setting this option to true will delay parsing of all table cell data until the user initializes a sort. This speeds up the initialization process of very large tables, but the data still needs to be parsed, so the delay is still present upon initial sort.
<li><code>emptyMax</code> - sort empty table cells as having a value greater than the <em>max</em> (more positive) value (<spanclass="version">v2.16.2</span>).</li>
<li><code>emptyMin</code> - sort empty table cells as having a value greater than the <em>min</em> (more negative) value (<spanclass="version">v2.16.2</span>).</li>
For example, to disable sorting on the first two columns of a table: <code>headers: { 0: { sorter: false}, 1: {sorter: false} }</code>.<br>
<br>
The plugin attempts to detect the type of data that is contained in a column, but if it can't figure it out then it defaults to alphanumeric. You can easily override this by setting the header argument (or column parser).
See the full list of <ahref="#parsers">default parsers</a> here or <ahref="example-parsers.html">write your own</a>.
Please note that the headers index values corresponds to the table header cells index (zero-based) and <strong>not</strong> the actual columns. For example, given the following table <code>thead</code> markup, the <code>header-index</code> counts the header <code>th</code> cells and does not actually match the <code>data-column</code> index when extra rows and/or <code>colspan</code> or <code>rowspan</code> are included in any of the header cells:
So, in the above example, to disable the sort of the second table column (<code>data-column</code> index of 1), the header cell of index 2 needs to be set as follows: <code>2 : { sorter : false }</code>.<br>
<br>
In <spanclass="version updated">v2.17.0</span>, you can reference the column(s) using a class name, id or column index.
<spanclass="label label-warning">Warning</span> What <em>won't work</em> is if you try to target the header using a filtering selector that uses an index, e.g. <code>"th:eq()"</code>, <code>":gt()"</code>, <code>":lt()"</code>, <code>":first"</code>, <code>":last"</code>, <code>":even"</code> or <code>":odd"</code>, <code>":first-child"</code>, <code>":last-child"</code>, <code>":nth-child()"</code>, <code>":nth-last-child()"</code>, etc.
<td>This is a template string which allows adding additional content to the header while it is being built (v2.7; <spanclass="version updated">v2.17.8</span>).
In <spanclass="version updated">v2.17.8</span>, if this option is set to an empty string (<code>''</code>), an inner div will no longer be wrapped around the header content.<br>
<code>{content}</code> will be replaced by the current header HTML content.<br>
<code>{icon}</code> will be replaced by <code><i class="tablesorter-icon"></i></code>, but only if a class name is defined in the <code>cssIcon</code> option.<br>
After the template string is built, the <code>onRenderTemplate</code> function is called to allow further manipulation. Please read more about this <ahref="#onrendertemplate"><code>onRenderTemplate</code> function</a> and/or check out the example (link to the right).
Used by the image parser to grab the image attribute content (<spanclass="version">v2.17.5</span>; moved to tablesorter core in <spanclass="version updated">v2.18.0</span>; see <ahref="#parsers"><code>config.parsers</code></a>).
<divclass="collapsible"><br>
Change this setting to grab a different image attribute to be used for sorting:
<preclass="prettyprint lang-js">$(function(){
$('table').tablesorter({
// parse image title (value to be used while sorting & filtering)
imgAttr : 'title',
headers : {
0 : { sorter: 'image' } // this parser is auto-detected, but will only work on the first image
});</pre><small>* Note: bind to all initialization events before initializing tablesorter; because most of the time, if bound after, the events will fire before the binding occurs</small>.</div>
<td>Apply widgets after table initializes (v2.3.5).
<divclass="collapsible">
When true, all widgets set by the <code>widgets</code> option will apply after tablesorter has initialized, this is the normal behavior.<br>
<br>
If false, the each widget set by the <code>widgets</code> option will be initialized, meaning the "init" function is run, but the format function will not be run. This is useful when running the pager plugin after the table is set up. The pager plugin will initialize, then apply all set widgets.<br>
<br>
Why you ask? Well, lets say you have a table with 1000 rows that will have the pager plugin applied to it. Before this option, the table would finish its setup, all widgets would be applied to the 1000 rows, pager plugin initializes and reapplies the widgets on the say 20 rows showing; making the widget application to 100 rows unnecessary and a waste of time. So, when this option is false, widgets will only be applied to the table after the pager is set up.
<td>When the table has a class name that matches the template and a widget id that matches the <code>{name}</code>, the widget will automatically be added to the table (<spanclass="version">v2.18.0</span>)
<divclass="collapsible">
<br>
By default, this option is set to <code>'widget-{name}'</code>. So if the table has a class name of <code>widget-zebra</code> the zebra widget will be automatically added to the <code>config.widgets</code> option and applied to the table.<br>
<br>
Some widget ID's with special characters may not be detected; ID's with letters, numbers, underscores and/or dashes will be correctly detected.<br>
<br>
The template string *must* contain the <code>{name}</code> tag.
This function is called after content is to the TH tags (after the template is procressed and added). You can use this to modify the HTML in each header tag for additional styling (<spanclass="version updated">v2.18.0</span>).
In versions 2.0.6+, all TH text is wrapped in a div with a class name of "tablesorter-inner" by default. In the example below, the header cell (TH) div is given a class name (<ahref="http://www.pengoworks.com/workshop/jquery/tablesorter/tablesorter.htm">source</a>).<br>
Function parameters:
<ul>
<li><code>index</code> - zero-based index of the current table header cell; this value is <em>not</em> indicative of the column index, as it is simply a count of header cells. So it will be effected by rowspan, colspan and multiple rows in the header.</li>
<li><code>config</code> - The current <code>table.config</code>.</li>
<li><code>$table</code> - This value is the current table jQuery object. If this function is being applied to cloned headers, as is does in the stickyHeaders widget, then this value will contain the sticky header clone added after the current table, and not the main table (<spanclass="version">v2.18.0</span>).</li>
<small>* Note: this function adds additional rendering time to the table if any DOM manipulation is done. Because this time will be on top of the processing time already added by the template.</small>
This function is called after the template string has been built, but before the template string is applied to the header and before the <code>onRenderHeader</code> function is called (v2.7).
The <code>onRenderTemplate</code> function receives a column index and template string parameters. The template string, from the <ahref="#headertemplate"><code>headerTemplate</code> option</a>, will already have the <code>{icon}</code> and <code>{content}</code> tags replaced; it's just a string of formatted HTML. When done manipulating this string, return it. Here is an example:
});</pre>The <code>template</code> parameter can be manipulated as a string, or if you prefer, turn it into a jQuery object (<code>var $t = $(template)</code>) to find and replace content as desired. Just make sure you return a string (<code>return $t.html()</code>)<br>
From the example function above, you'll end up with something similar to this HTML (only the thead is shown)<preclass="prettyprint lang-html"><thead>
<br>Added <code>></code> to the selector in v2.3 to prevent targetting nested table headers. It was modified again in v2.4 to include <code>td</code> cells within the thead.
<td>This CSS class name can be applied to all rows that are to be removed prior to triggering a table update. (v2.1).
<divclass="collapsible">
<br>
It was necessary to add this option because some widgets add table rows for styling (see the <ahref="example-widgets.html">writing custom widgets demo</a>) and if a table update is triggered (<code>$('table').trigger('update');</code>) those added rows will automatically become incorporated into the table.
<td>When this option is <code>true</code> any applied sort on the table will be reapplied after an update method (<spanclass="version">v2.19.0</span>).
Specifically, this option applies to the "updateAll", "update", "addRows" and "updateCell" methods and is checked after the method has completed updating the internal cache.<br>
<spanclass="label label-info">Note</span> when triggering one of the above methods, and passing a defined <code>resort</code> parameter, it will override this setting.<br>
<br>
<spanclass="label label-warning">Note</span> if a sort is not reapplied, problems with some widgets may occur namely the grouping widget.
<td>Show an indeterminate timer icon in the header when the table is sorted or filtered. Please note that due to javascript processing, the icon may not show as being animated. I'm looking into this further and would appreciate any feedback or suggestions with the coding (v2.4).</td>
<td>Use to add an additional forced sort that is <strong>prepended</strong> to <ahref="#sortlist"><code>sortList</code></a>.
<divclass="collapsible">
<br>
For example, <code>sortForce: [[0,0]]</code> will sort the first column in ascending order. After the forced sort, the user selected column(s), or during initialzation, the sorting order defined in the sortList will follow. And lastly, the sort defined in the <ahref="#sortappend"><code>sortAppend</code></a> option will be applied. More explicitly:<br>
<br>
There are three options to determine the sort order and this is the order of priority:
<ol>
<li><ahref="#sortforce"><code>sortForce</code></a> forces the user to have this/these column(s) sorted first (null by default).</li>
<li><ahref="#sortlist"><code>SortList</code></a> is the initial sort order of the columns.</li>
<li><ahref="#sortappend"><code>SortAppend</code></a> is the default sort that is added to the end of the users sort selection (null by default).</li>
</ol>
The value of these sort options is an array of arrays and can include one or more columns. The format is an array of instructions for per-column sorting and direction in the format: <code>[[columnIndex, sortDirection], ... ]</code> where <code>columnIndex</code> is a zero-based index for your columns left-to-right and <code>sortDirection</code> is 0 for Ascending and 1 for Descending. A valid argument that sorts ascending first by column 1 and then column 2 looks like: <code>[[0,0],[1,0]]</code>.

Setting this option to <code>true</code> will allow you to click on the table header a third time to reset the sort direction. (v2.0.27).
<divclass="collapsible">
<br>Don't confuse this option with the <ahref="#sortreset-method"><code>sortReset</code> method</a>. This option only resets the column sort after a third click, while the method immediately resets the entire table sort.

<li><code>"none"</code> or <code>"zero"</code> will treat the text as if it has a value of zero.</li>
Changed to empty string in v2.11, as the <code>"tablesorter"</code> class will always be added to the table; this option now contains any additional class names to add.
<p>This class was required in the default markup in version 2.0.5. But in version 2.0.6, it was added as an option.</p>

<li>Also, this option can now be set using a data-attribute named "data-text-extraction" on the table.</li>
tablesorter will pass the current table cell object for you to parse and return. Thanks to Josh Nathanson for the examples; updated to a jQuery example by Rob G (Mottie).
<p>Now if the text you are finding in the script above is say a number, then just include the <ahref="#headers"><code>headers</code></a> sorter option to specify how to sort it. Also in this example, we will specify that the special textExtraction code is only needed for the second column (<code>1</code> because we are using a zero-based index). All other columns will ignore this textExtraction function.</p>
<p>Added <code>table</code> and <code>cellIndex</code> variables to the <code>textExtraction</code> function in version 2.1.2 (this is not part of the original plugin).</p>
The built-in option is <code>"basic"</code> (modified v2.16.0) which is the equivalent of doing this inside of the textExtraction function: <code>$(node).text();</code>.
});</pre>The direction parameter (boolean) is merely for informational purposes as the plugin automatically switches <code>a</code> and <code>b</code> depending on the sort direction ( i.e. there's no need to worry about reverse sorting, it's taken care of by the plugin ).
Replace the default sorting algorithm with a custom one using this option (<spanclass="version updated">v2.12</span>) - <spanclass="label label-warning">*NOTE*</span> The parameters have changed!!.
});</pre>The direction parameter (boolean) is merely for informational purposes as the plugin automatically switches <code>a</code> and <code>b</code> depending on the sort direction ( i.e. there's no need to worry about reverse sorting, it's taken care of by the plugin ).
Initialize widgets using this option ( e.g. <code>widgets : ['zebra']</code>, or custom widgets <code>widgets: ['zebra', 'myCustomWidget'];</code>, see <ahref="example-widgets.html">this demo</a> on how to write your own custom widget ).
In version 2.1, all widget options have been moved into this option. This is a move to store all widget specific options in one place so as not to polute the main table options. All current widgets have been modified to use this new option. (v2.1).
<divclass="collapsible">
<br>
Previously documented widget options <ahref="#widgetzebra"><code>widgetZebra</code></a>, <ahref="#widgetcolumns"><code>widgetColumns</code></a> and <ahref="#widgetuitheme"><code>widgetUitheme</code></a> will be retained for backwards compatibility.<br>
<br>
Use the <ahref="#widgetoptions"><code>widgetOptions</code></a> option as follows, please note that each option is followed by a comma (except the last one):
This option was added to set a specific page when storing data using the <ahref="#function-storage"><code>$.tablesorter.storage</code></a> code (<spanclass="version">v2.12</span>).
More specifically, when the storage function is used, it attempts to give every table a unique identifier using both the page <strong>url</strong> and table <strong>ID</strong> (or index on the page if no id exists). This option allows you to override the current page url (<em>it doesn't need to be a url, just some constant value</em>) and save data for multiple tables across a domain.<br>
<br>
The table url & id can also be overridden by setting table data attributes <code>data-table-page</code> (url) and <code>data-table-group</code> (id)<br>(e.g. <code><table class="tablesorter" data-table-page="mydomain" data-table-group="financial">...</table></code>)<br>
<br>
For a bit more detail, specifically on how to use the new storage function options for a custom widget, please refer to <ahref="https://github.com/Mottie/tablesorter/issues/389#issuecomment-26594259">issue #389</a>.
When the column styling widget is initialized, it automatically applied the default class names of <code>"primary"</code> for the primary sort, <code>"secondary"</code> for the next sort, <code>"tertiary"</code> for the next sort, and so on (add more as needed)... (v2.0.17).
Used when the ui theme styling widget is initialized. It automatically applies the default class names of <code>"ui-icon-arrowthick-2-n-s"</code> for the unsorted column, <code>"ui-icon-arrowthick-1-s"</code> for the descending sort and <code>"ui-icon-arrowthick-1-n"</code> for the ascending sort. (v2.0.9).

Use the <ahref="#widgetuitheme"><code>widgetUitheme</code></a> option to change the css class name as follows:
When the zebra striping widget is initialized, it automatically applied the default class names of <code>"even"</code> and <code>"odd"</code>.
tablesorter widgets have many options, and to better organize them, they now are grouped together inside of the <code>widgetOptions</code>. Thanks to thezoggy for putting together this jQuery-widget compatibility table, but please note:
<li>The applied order of widget is dependent of the widget priority, from low to high.</li>
<li>Widget priority values do not need to be unique. Any new widget without a defined priority will automatically have a priority of <code>10</code>.</li>
<li>* The <code>saveSort</code> and <code>resizable</code> widgets use the <ahref="#function-storage"><code>$.tablesorter.storage</code></a> function by default and thus need the <code>parseJSON</code> function which is available in jQuery 1.4.1+.</li>
<li>** The <code>stickyHeaders</code> widget was updated in v2.18.0 to use <code>$.isWindow</code> for the <code>xScroll</code>&<code>yScroll</code> options; and therefore now requires jQuery 1.4.3+.</li>
<spanclass="label label-info">TIP!</span> Click on the link in the property column to reveal full details (or <ahref="#"class="toggleAll">toggle</a>|<ahref="#"class="showAll">show</a>|<ahref="#"class="hideAll">hide</a> all) or double click to update the browser location.
Columns widget: When the column styling widget is initialized, it automatically applied the default class names of <code>"primary"</code> for the primary sort, <code>"secondary"</code> for the next sort, <code>"tertiary"</code> for the next sort, and so on (add more as needed)... (Modified v2.1).
Columns widget: If true, the class names from the <ahref="#widget-columns"><code>columns</code></a> option will also be added to the table thead (v2.4).
Columns widget: If true, the class names from the <ahref="#widget-columns"><code>columns</code></a> option will also be added to the table tfoot (v2.4).
Filter widget: If there are child rows in the table (rows with class name from <ahref="#csschildrow"><code>"cssChildRow"</code></a> option) and this option is <code>true</code> and a match is found anywhere in the child row, then it will make that row visible.
<td>Additional CSS class applied to each filter cell (<spanclass="version">v2.18.0</span>).
<divclass="collapsible"><br>
When the filter row is built, each table cell (<code><td></code>) will get the class name from this option.
<ul>
<li>If this option is a plain string, all filter row cells will get the text applied as a class name.</li>
<li>If this option is an array, then each filter row cell will get the text from the associate array element applied as a class name.</li>
</ul>
<p>Use the <ahref="#widget-filter-cellfilter"><code>filter_cellFilter</code></a> option to add an extra css class name as follows:</p>
<preclass="prettyprint lang-js">$(function(){
$("table").tablesorter({

Filter widget: Add a default filter type to a column (<spanclass="version">v2.17.8</span>).
<divclass="collapsible">
<br>
<spanclass="label warning">Warning</span> If a column has a default filter set, the user <strong>will not</strong> be able to use other filters.<br>

5 : '{q} or {q}' // any match column
}
}
});
});</pre>
Set up the column string as follows:
<ul>
<li>Add the desired filter type symbol along with <code>{query}</code> or <code>{q}</code> to maintain positioning</li>
<li>Symbols can be added to the beginning <code>"~{query}"</code> (default fuzzy search) or end <code>"{q}="</code> (default exact search)</li>
<li>For symbols that separate queries, like "AND", "OR" or "-" (range):
<ul>
<li>Add one additional <code>{q}</code> tag.</li>
<li>For example, to add a default "OR" search, use <code>"{q} OR {q}"</code>.</li>
<li>If the user enters <code>"a b c d"</code> the column will be filtered using <code>"a OR b OR c OR d"</code>, so there is no need to add more <code>{q}</code> tags within the string; adding more will likely mess up the results.</li>
<li>If the user only enters <code>"a"</code>, then the column will be filtered using <code>"a OR a"</code> so as not to cause other issues.</li>
</ul>
</li>
<li><spanclass="label label-info">Note</span> It is not possible to set up a default filter search within a query. So the "wild" filter search will not work as intended (e.g. <code>{q}*</code> and <code>{q}?</code> are essentially the same as <code>{q}</code>.</li>
<li><code>wild</code> - wild card matching (<code>?</code> for single characters, <code>*</code> for multiple characters not including spaces, or <code>|</code> or <code> OR </code> for a logical OR.</li>
Filter widget: jQuery selector string of inputs, outside of the table, to be used for searching table content (<spanclass="version">v2.15</span>).
<divclass="collapsible">
<br>
Set this option to be a jQuery selector string, or jQuery object, pointing to any external inputs that are to be used for searching the table.<br>
<br>
Use the <ahref="#widget-filter-external"><code>filter_external</code></a> option as follows:
<preclass="prettyprint lang-js">$(function(){
$("table").tablesorter({
widgets: ["filter"],
widgetOptions : {
filter_external : '.search'
}
});
});</pre>
These external inputs have one requirement, they must have a <code>data-column="#"</code>, where the <code>#</code> targets the column (zero-based index), pointing to a specific column to search.<br>
<preclass="prettyprint lang-html"><input class="search" type="search" data-column="0" placeholder="Search first column"></pre>
If you want to search all columns, using the updated "any match" method, set the data column value to "all":<br>
Filter widget: This is the class name applied to all rows that do not match the filter (hidden rows); used by pager plugin (<spanclass="version">v2.10</span>).
In <spanclass="version updated">v2.17.0</span>, the <code>filter_formatter</code> column can also be referenced by using a jQuery selector (e.g. class name or ID) that points to a table <em>header</em> cell.<br>
<spanclass="label label-warning">Warning</span> What <em>won't work</em> is if you try to target the header using a filtering selector that uses an index, e.g. <code>"th:eq()"</code>, <code>":gt()"</code>, <code>":lt()"</code>, <code>":first"</code>, <code>":last"</code>, <code>":even"</code> or <code>":odd"</code>, <code>":first-child"</code>, <code>":last-child"</code>, <code>":nth-child()"</code>, <code>":nth-last-child()"</code>, etc.<br>
A new file has been included named "widget-filter-formatter-jui.js" & "widget-filter-formatter-html5.js". The files include code to add jQuery UI and HTML5 controls via the <ahref="#widget-filter-formatter"><code>filter_formatter</code></a> option.<br>
Most of the formatter functions have an option named <code>valueToHeader</code> which, when <code>true</code> adds a span to the header cell above the filter row and updates it with the current control's value (see <ahref="example-widget-filter-formatter-2.html">example 2</a>). If the option exists and is set to <code>false</code>, then the current value is added to the control's handle and css can be used to create a popup to show the current value (see <ahref="example-widget-filter-formatter-1.html">example 1</a>).<br>
<br>
Another custom option named <code>addToggle</code> is included with the "uiSpinner", "html5Color" and "html5Number" code. This allows the user to disable the control to show all table rows. For the single sliders, "uiSlider" and "html5Range", the minimum value is used to clear the filter (show all rows).<br>
<br>
The options included for each jQuery UI control only show basic options, but any or all of the jQuery UI options for that control can be included.<br>
For other examples, please refer to the example pages. Formatter part 1 (example 1) adds jQuery UI controls to the filter row, while formatter part 2 (example 2) adds HTML5 controls, if supported, to the filter row.
Filter widget: Customize the filter widget by adding a select dropdown with content, custom options or custom filter functions (v2.3.6; <spanclass="version updated">v2.17.0</span>).
In <spanclass="version updated">v2.17.0</span>, the <code>filter_functions</code> column can also be referenced by using a jQuery selector (e.g. class name or ID) that points to a table <em>header</em> cell.<br>
<spanclass="label label-warning">Warning</span> What <em>won't work</em> is if you try to target the header using a filtering selector that uses an index, e.g. <code>"th:eq()"</code>, <code>":gt()"</code>, <code>":lt()"</code>, <code>":first"</code>, <code>":last"</code>, <code>":even"</code> or <code>":odd"</code>, <code>":first-child"</code>, <code>":last-child"</code>, <code>":nth-child()"</code>, <code>":nth-last-child()"</code>, etc.<br>
// set the column value to true, and/or add "filter-select" class name to header
0 : true
}
}
});
});</pre>
Alternately, instead of setting the column filter funtion to true, give the column header a class name of "filter-select". See the <ahref="example-widget-filter-custom.html">demo</a>.<br><br>
</li>
<li>
Make a select dropdown list with custom option settings. Each option must have a corresponding function which returns a boolean value; return true if there is a match, or false with no match.
Filter widget: Set this option to <code>false</code> to always show the filter row; by default, the filter row is completely hidden when no rows exist within the tbody (<spanclass="version">v2.15</span>).
<divclass="collapsible">
<br>
Use the <ahref="#widget-filter-hideempty"><code>filter_hideEmpty</code></a> option as follows:
Filter widget: Set this option to <code>true</code> to hide the filter row initially. The row is revealed by hovering over the visible portion of the filter row or by giving any filter input/select focus (tab key) (v2.4).
});</pre>You can change the style (thickness) of the hidden filter row in the tablesorter theme css. Look for <code>.tablesorter-filter-row</code> (revealed row) and <code>.tablesorter-filter-row.hideme</code> (for the hidden row) css definitions.</div>
Filter widget: Set this option to <code>false</code> to make the column content search case-sensitive, so typing in "a" will not find "Albert". (v2.3.4)
Filter widget: If <code>true</code>, a search of the column content will occur as the user types, with the delay set in the <code>filter_searchDelay</code> option (v2.9; <spanclass="version updated">v2.10</span>).
This option, when <code>false</code> allows you to disable the live search behavior, so that a filter is only applied when the user presses <kbd>Enter</kbd> (or uses <kbd>Esc</kbd> to clear and cancel the search).<br>
If this option is set to a number, e.g. <code>4</code>, a search of the column content will not initiate until this minimum number of characters are entered into the input.
Filter widget: If a header contains a select dropdown and this class name, only the available (visible) options in the column will show (<spanclass="version">v2.10.1</span>; <spanclass="version updated">v2.17.6</span>).
In <spanclass="version">v2.17.6</span>, columns with the only available class name set, that <em>are not</em> currently being filtered will only show the available options. Conversely, the column(s) with a selected option will show all options.<br>
This option is useful after one or more columns have been filtered, then the column select filter with this class applied will only show the contents of the column within the dropdown that are currently visible. See the <ahref="example-widget-filter-custom.html">custom filter widget</a> demo "Discount" column for an example (sort the "First Name" column first).<br>
<spanclass="label label-warning">Caution:</span> The main issue with this functionality is with keyboard accessibility. If the keyboard is used to select an option, only the first and default options will be available for chosing. The only way to select other options is with the mouse.
Filter widget: Set global filter input placeholder text for search inputs and selects (<spanclass="version">v2.16</span>).
<divclass="collapsible">
<br>
Any search type input added to the filter row will automatically get a placeholder attribute added, the source of this placeholder text is from the following sources, in order of priority:
<ul>
<li>Header cell data (<code>table.config.$headers.eq(0).data('placeholder', 'search for...');</code></li>
<spanclass="label label-info">Note:</span> The <code>widget-filter-formatter-jui.js</code> jQuery UI Datepicker Range Selector creates two inputs, so this option then includes two additional settings:<br>
</pre><spanclass="label label-info">Note:</span> The browser must support the <ahref="http://caniuse.com/#feat=input-placeholder">placeholder attribute</a> before it will be visible.
When this option points to a reset element using a jQuery selector string, it is bound using <ahref="http://api.jquery.com/on/#direct-and-delegated-events">event delegation</a>. So if any additional reset elements, with the same class name, are added to the page dynamically, they will be associated with the same table.<br>
<br>
For example, add this button (<code><button class="reset">Reset</button></code>) to the table header, or anywhere else on the page. That element will be used as a reset for all column and quick search filters (clears all fields):
If this option contains a jQuery object (<spanclass="version">v2.16</span>), clicking on any of the elements within that jQuery object will trigger a filter reset. If any additional elements with the same selector are added to the page, they will not be dynamically functional.<br>
<br>
If either of these methods do not work as desired, simply trigger a <ahref="#filterreset"><code>filterReset</code> event</a> on the table.
Filter widget: If the storage utility is available (included with <code>jquery.tablesorter.widgets.js</code> file, the last applied filter is saved to storage (<spanclass="version">v2.14</span>).
Filters saved to local storage (or cookies) will override any default filters within the header data-attribute (set by the <ahref="#widget-filter-defaultattrib"><code>filter_defaultAttrib</code> option</a> and be available to the pager before any ajax calls are made.<br>
Filter widget: Set this option to allow searching through already filtered rows (in special conditions); this will speed up searching in large tables (<spanclass="version">v2.17.4</span>).
<divclass="collapsible">
<br>
To better explain this, lets do it by example. Lets say you have a column of color names and you enter "light" and results like "light blue" and "light grey" show up.<br>
<br>
When you press the space bar, a space is added, and instead of searching though all of the colors again, the filter widget only searches through the already filtered results that started with "light". This can substantially speed up searching, especially in large tables.<br>
<br>
But, there are some special circumstances which would make this method return incorrect results. So, this option was added to allow you to disable this feature in case one of these following conditions doesn't cover your need; but still, please report any issues!<br>
<br>
The search through filtered results <em>only occurs</em> if the following conditions are met:
<ul>
<li>The last search (for all columns) was not completely empty - all rows will be searched anyway.</li>
<li>If there were no changes to the search from the beginning of the search string (changing the above search to "bright" will force a new search of all rows).</li>
<li>If the search does not contain a logical or (<code> or </code> or <code>|</code>), or a range delimiter (<code> - </code> or <code> to </code>) within the search query.</li>
<li>If the search is not looking for an exact match (<code>"</code> or <code>=</code>) or a logical not search (<code>!</code>).</li>
<li>Or, if the search is using a select dropdown without a "filter-match" class name (looking for an exact match).</li>
<li>If the search does not contain an operator greater than or equal to a negative number (<code>>=-10</code>) or less than or equal to a positive number (<code><=10</code>).</li>
<li>And lastly, only search filtered rows if all rows are not hidden.</li>
</ul>
If the <code>debug</code> option is set to <code>true</code>, then a message will appear while filtering stating the specific number of rows, or "all" rows, that are being searched.<br>
<br>
Use the <ahref="#widget-filter-searchfiltered"><code>filter_searchFiltered</code></a> option as follows:
Filter widget: Include a function to return an array of values to be added to the column filter select (<spanclass="version">v2.16.0</span>; <spanclass="version updated">v2.17.2</span>).
In <spanclass="version updated">v2.17.0</span>, the <code>filter_selectSource</code> column can also be referenced by using a jQuery selector (e.g. class name or ID) that points to a table <em>header</em> cell.<br>
<spanclass="label label-warning">Warning</span> What <em>won't work</em> is if you try to target the header using a filtering selector that uses an index, e.g. <code>"th:eq()"</code>, <code>":gt()"</code>, <code>":lt()"</code>, <code>":first"</code>, <code>":last"</code>, <code>":even"</code> or <code>":odd"</code>, <code>":first-child"</code>, <code>":last-child"</code>, <code>":nth-child()"</code>, <code>":nth-last-child()"</code>, etc.<br>
A column will have a filter select dropdown when a "filter-select" class name is added to the header cell, or if the <ahref="#widget-filter-functions"><code>filter_functions</code></a> column value is set to <code>true</code><br>
<br>
This option allows using an alternate source, or customizing options of the filter select dropdown. This option can be set as follows:
<ul>
<li><code>null</code> - this value will set the default behavior and return all table cell values from the current column.</li>
<li>An overall function - when this option is a function, it will be used for all filter selects in the table.
<li><code>column</code> - zero-based index of the column with a filter select</li>
<li><code>onlyAvail</code> - boolean indicating if the returned options should only be from available (non-filtered) rows.</li>
</ul>
<spanclass="label label-info">Important</span> Return an array of values which will be added to the filter select dropdown. This array will automatically be stripped of any duplicate values and sorted alphanumerically before being added to the select. If for some reason the custom <code>filter_selectSource</code> function does not obtain the desired array of values, return <code>false</code> and the original method of obtaining column cell content will be used.
Filter widget: Set this option to be any separator (<spanclass="version">v2.17.6</span>) that is to be used within the <code>filter_selectSource</code> returned array.
<divclass="collapsible">
<br>
Use the <ahref="#widget-filter-selectsource-separator"><code>filter_selectSourceSeparator</code></a> option as follows:
<preclass="prettyprint lang-js">$(function(){
$("table").tablesorter({
widgets: ["filter"],
widgetOptions : {
filter_selectSource : {
0 : [ 'en|English', 'fr|French', 'de|German' ]
},
// filter_selectSource array text left of the separator is added to the option value, right into the option text
Filter widget: Set this option to <code>true</code> to use the filter to find text from the start of the column, so typing in "a" will find "albert" but not "frank", both have a's. (v2.1).
<li>To only use parsed data in specific columns, set this option to <code>false</code> and use any of the following (they all do the same thing), set in order of priority:
<li>Remember that parsed data most likely doesn't match the actual table cell text, <code>20%</code> becomes <code>20</code> and <code>Jan 1, 2013 12:01 AM</code> becomes <code>1357020060000</code>.</li>
Filter widget: This option contains the name of the data-attribute which contains the default (starting) filter value (<spanclass="version">v2.10.8</span>).
<divclass="collapsible">
<br>
Use the <ahref="#widget-filter-defaultattrib"><code>filter_defaultAttrib</code></a> option as follows:

Changed to empty string in v2.11, as the <code>"tablesorter-stickyHeader"</code> class will always be added to the sticky header row; this option now contains any additional class names to add.
Sticky Headers widget: If the table has an ID defined, the suffix from this option will be added to the ID in the cloned sticky table (<spanclass="version">v2.9</span>).
Sticky Headers widget: If this option is <code>false</code> and a caption exists, it will not be included in the sticky header (<spanclass="version">v2.10.8</span>).
<divclass="collapsible">

Use the <ahref="#widget-sticky-headers-include-caption"><code>stickyHeaders_includeCaption</code></a> option as follows:
Sticky Headers widget: points to the table wrapper to stick the headers to while scrolling. Use this option to point to their needs (<spanclass="version">v2.14.4</span>).

Use the <ahref="#widget-sticky-headers-attachto"><code>stickyHeaders_attachTo</code></a> option as follows:<br>
Sticky Headers widget: Set the sticky header offset from the top as a <em>Number</em> or jQuery selector <em>string</em> or <em>object</em> (<spanclass="version">v2.10</span>).
If the page includes a fixed navigation bar at the top, like Bootstrap, set <ahref="#widget-sticky-headers-offset"><code>"stickyHeaders_offset"</code></a> option to offset the sticky table header to be below the fixed navigation by setting this option using any of the following examples:<br>
Sticky Headers widget: Scroll table top into view after filtering (<spanclass="version">v2.16.2</span>).
<divclass="collapsible">
<br>
When a user searches the table using the sticky header filter row the results may reduce the number of rows so that the table would scroll up out of the viewport. So, this option scrolls the table top into view and moves the filter focus to the same input in the original header, instead of the sticky header input.<br>
<br>
Set this option to <code>false</code> to prevent the page scroll after filtering the table.
Sticky Headers widget: If <code>true</code>, sticky table headers will resize automatically when content is added to or removed from the table headers (<spanclass="version">v2.10</span>).
<divclass="collapsible">
<br>
While this option is <code>true</code>, a timer is initialized to check the width of every header cell every 1/4 second. If this causes lag, or any other problems, set this option to <code>false</code>.
When this option is <code>false</code>, sticky table headers are unable to detect and match the width of the original table headers when content is added or removed.<br>
Sticky Headers widget: The zIndex added to the stickyHeaders. This option allows the user to adjust the value to their needs (<spanclass="version">v2.11</span>).
<divclass="collapsible">

Use the <ahref="#widget-sticky-headers-zindex"><code>stickyHeaders_zIndex</code></a> option as follows:
Resizable widget: If this option is set to <code>false</code>, resized column widths will not be saved. Previous saved values will be restored on page reload (v2.4).
Resizable widget: If this option is set to <code>true</code>, a resizing anchor will be included in the last column of the table (<spanclass="version">v2.8.3</span>).
If an anchor was included and the table is full width, the column would resize in the opposite direction which my not be intuitive to the user. So set this option as desired, but please be mindful of the user experience.<br>

Use the <ahref="#widget-resizable-throttle"><code>"resizable_widths"</code></a> option as follows:
saveSort widget: If this option is set to <code>false</code>, new sorts will not be saved. Any previous saved sort will be restored on page reload (v2.4).
zebra widget: When the zebra striping widget is initialized, it automatically applied the default class names of <code>"even"</code> and <code>"odd"</code>. (Modified v2.1).
<spanclass="label label-info">Note</span> The pager widget equivalent option is within the <code>widgetOptions</code> and accessed via <code>widgetOptions.pager_selectors.container</code>; additionally you can change the class name that is applied to the pager (used within the <code>jquery.tablesorter.pager.css</code> file) by modifying the <code>widgetOption.pager_css.container</code> class name (default is <code>"tablesorter-pager"</code>)<br>
This is some example pager markup. It <em>should</em> contain all of the controls set by the multiple css-named options:<preclass="prettyprint lang-html">

Set this option to include a url template to use so that the pager plugin can interact with your database (v2.1; <spanclass="version updated">v2.9</span>).
<spanclass="label label-info">Note</span> The pager widget equivalent option is within the <code>widgetOptions</code> and accessed via <code>widgetOptions.pager_ajaxUrl</code><br>
The tags within the <code>ajaxUrl</code> string are optional. If do not want the user to change the page size, then you only need to include the page in this string:
If you need to send your server a page offset (actual starting record number), then you'll need to use the <ahref="#pager-customajaxurl"><code>customAjaxUrl</code> option</a>.<br>
<tr><td><code>{page+1}</code></td><td>One-based index of the current pager page (replace "+1" with any number) (e.g. <code>{page+3}</code>) (<spanclass="version">v2.9</span>).</td></tr>
The <code>col</code> portion of the <code>{sortList:col}</code> tag can be any name string (no spaces) to indicate the name of the variable to apply. So if your current sortList is <code>[[2,0],[3,0]]</code>, it becomes <code>"&sort[2]=0&sort[3]=0"</code> in the url. <code>{sort:col}</code> shortened tag also works (<spanclass="version">v2.9</span>).
<td>Adds the value of the current filters to the ajax url string into a "fcol" array, so your server-side code knows how to filter the data (v2.6).<br>
The <code>fcol</code> portion of the <code>{filterList:fcol}</code> tag can be any name string (no spaces) to indicate the name of the variable to apply. So if your current filters are <code>['','Blue',13]</code>, it becomes <code>"&fcol[2]=Blue&fcol[3]=13"</code> in the url. <code>{filter:col}</code> shortened tag also works (<spanclass="version updated">v2.9</span>).
This callback function allows you to modify the processed URL as desired (<spanclass="version">v2.8.1</span>) <spanclass="label label-info">docs updated</span>.
<spanclass="label label-info">Note</span> The pager widget equivalent option is within the <code>widgetOptions</code> and accessed via <code>widgetOptions.pager_customAjaxUrl</code><br>
The <code>customAjaxUrl</code> function has two parameters, the table DOM element and the processed url string (all tags within the <code>ajaxUrl</code> have been replaced with their appropriate values).
In the following example, lets say your server needs a starting and ending record number instead of a page & size parameter. Use this option as follows:
<spanclass="label label-info">Note</span> The pager widget equivalent option is within the <code>widgetOptions</code> and accessed via <code>widgetOptions.pager_ajaxObject</code><br>
The <code>ajaxObject</code> is completely customizable, except for the <code>url</code> setting which is processed using the pager's <code>ajaxUrl</code> and <code>customAjaxUrl</code> options. This means you can also add a <code>success</code> callback function which is called after the ajax has rendered.<br>
Your server does not need to return a JSON format, if you want to return pure HTML, set the dataType to <code>"html"</code> and modify the <code>ajaxProcessing</code> function to instead work with HTML; then return a jQuery object or apply the HTML to the table yourself.<br>
Set this option to <code>false</code> if your table data is preloaded into the table, but you are still using ajax (<spanclass="version">v2.14.5</span>).
<spanclass="label label-info">Note</span> The pager widget equivalent option is within the <code>widgetOptions</code> and accessed via <code>widgetOptions.pager_processAjaxOnInit</code>
This function is required to return the ajax data obtained from your server into a useable format for tablesorter to apply to the table (v2.1, <spanclass="version updated">v2.17.3</span>).
<spanclass="label label-info">Note</span> The pager widget equivalent option is within the <code>widgetOptions</code> and accessed via <code>widgetOptions.pager_ajaxProcessing</code><br>
This function was created and modified to allow you a great deal of flexibility. The only required information that this function needs to return is an array containing the total number of rows, which is needed to calculate total pages.<br>
<br>
There are numerous examples below. Choosing which one to use is left to you. For more information, please check out related questions on <ahref="http://stackoverflow.com/search?q=%5Btablesorter%5D+ajaxProcessing">Stackoverflow</a>, in particular see <ahref="http://stackoverflow.com/q/16783740/145346">this thread</a> about how to use the different ajax options together.<br>
In <spanclass="version">v2.10</span>, the returned rows is now optional. And it can either be an array of arrays or a jQuery object (not attached to the table)<br>
Process your ajax data so that the following information is returned:<br>
<br>
<divclass="accordion">
<h3><ahref="#">Object</a></h3>
<div>
After tablesorter <spanclass="version updated">v2.17.3</span>, this function can include a <code>filteredRows</code> property which will update the internal value and thus show a proper filtered row count, and update the "goto" page drop down selector appropriately.<br>
<br>
After tablesorter <spanclass="version">v2.11</span>, the <code>ajaxProcessing</code> function can return an object containing these properties, along with any extra properties. These extra properties will be available for use within the pager <code>output</code> string (see more details in <ahref="https://github.com/Mottie/tablesorter/issues/326#issuecomment-25326546">issue #326</a>);<br>
<br>
So, lets say the data sent by the server looks like this:
This ajaxProcessing function must return an object with "total", "headers" and "rows" properties! As before, "total" is the only required property; if the headers don't need to be changed, don't return a headers array, and if you append the rows to the table yourself within the ajaxProcessing function, you don't need to return a "rows" property.
]</pre><spanclass="label label-info">Note</span>: In <spanclass="version">v2.14.3</span>, the contents of the array can also contain table cell markup (i.e. <code>"<td class='green'>+ 10%</td>"</code>).<br>

Also, use this method to add table rows while using the pager plugin. If the "update" method is used, only the visible table rows continue to exist.
Using this method will clear out any settings that have changed since the table was initialized (refreshes the entire table); so any sorting or modified widget options will be cleared.<br>
However, it will not clear any values that were saved to storage. This method is basically like reloading the page.
$('table').find('th:eq(2)').trigger('sort');</pre>Using this method will maintain the sorting order; so, if the column is already sorted in ascending order, this method will act as if you manually clicked on the header. Whatever sort order is applied is dependent on other option settings such as <code>initialSortOrder</code>, <code>lockedOrder</code> (set within the <code>headers</code>), <code>sortReset</code> option, <code>sortRestart</code> and will be ignored if the column sort is disabled (<code>sorter: false</code>).<br>

<li>When not using the "updateCell" or "addRows" methods.</li>
<li>Before manually adding or removing table rows.</li>
<li>And, before triggering an "update".</li>
</ul>
Note: The entire table is stored in the cache, but when using the pager with the <ahref="#pager-removerows"><code>removeRows</code> option</a> set to <code>true</code>, only the visible portion is actually exists within the table.

<li>In <spanclass="version updated">v2.16.0</span>, the last value in the column array is now an object which contains a jquery object of the row, index of the original unsorted order and a child array which contains raw html from any associated child row
<li>Well not removed, but moved into the row data, within the normalized section of the cache as described above.</li>
<li><del>This contains an array of jQuery row objects</del>.</li>
<li><del>These rows are never in sort order, and are used when updating the table after sorting the normalized content. The indexing of these rows is cross-referenced within the normalized values - the extra column value within the row array. Hopefully that makes sense</del>.</li>
This number is stored as a length (one-based), and takes into account any <code>colspan</code> and <code>rowspan</code> within the table head.<br>

Check out the <ahref="#headers"><code>headers</code></a> option to see how to use these parsers in your table (example #1).<br>Or add a header class name using "sorter-" plus the parser name (example #2), this includes custom parsers (example #3).
<td>Internal list of <strong>all</strong> extra table header cells (<spanclass="version">v2.16.2</span>)
<divclass="collapsible">
<br>
When the <ahref="#function-bindevents"><code>bindEvents</code></a> function is used, the extra (external) header cells are added to this variable, and automatically updated with the table headers (<ahref="#variable-headers"><code>config.$headers</code></a>).<br>
<br>
So, when writing a custom widget that clones the table header, there is no longer a need to update the header class names, it's all done automatically.
Some widgets need to duplicate parts of the original table to provide functionality (e.g. stickyHeaders, scroller). This saved variable will either not exist or contain a jQuery object pointing to the cloned table elements.<br>
<br>
This variable was added for the uitheme widget to allow dynamic updating of themes to the original table as well as all cloned parts.
The <code>table.config.$headers</code> variable contains ALL header cells, not all of which contain sorting information (data-attributes, class names or sorting information).
<p></p>
This variable targets the <em>last sortable header cell</em> in a particular column; unless an entire column is completely unsortable (checkbox column), then it just picks the last cell in that column.
<p></p>
To make that description less confusing, look at the HTML in the <ahref="#variable-headers"><code>config.$headers</code></a> documentation, only the four middle rows (header-index 1-4) will be contained within this variable:
<preclass="prettyprint lang-js">// the resulting config.$headerIndexed for the HTML example in config.$headers will look like this:
<spanclass="label label-warning">* NOTE *</span> This variable contains an array of jQuery objects, it is <em>not</em> a collection of jQuery objects, i.e.
The header cells are targeted using the jQuery selector from the <ahref="#selectorheaders"><code>selectorHeaders</code></a> option.<br>
<br>
Please note that the headers cells are simply an array of all header cells and should not be targeted using a column index. For example, given the following table <code>thead</code> markup, the <code>header-index</code> counts the header <code>th</code> cells and does not actually match the <code>data-column</code> index when extra rows and/or <code>colspan</code> or <code>rowspan</code> are included in any of the header cells:
So, in the above example, to target the header cell in the second table column (<code>data-column</code> index of 1), use the following code: <code>table.config.$headers.filter('[data-column="1"]')</code> or <code>table.config.$headers.eq(2)</code>.<br>
<br>
The <code>table.config.$headers</code> variable is useful within callback functions or when writing widgets that target the table header cells.
<td>Internally stored DOM table element (<spanclass="version">v2.17.5</span>)

The <code>table.config.table</code> variable is useful when certain callback functions only pass the config object; originally you could use <code>config.$table[0]</code>, but this saves that small extra trouble.

If using the pager plugin or widget, the value returned from the <code>filterEnd</code> event will not be accurate, so you'll need to bind to the <code>pagerComplete</code> event instead:
<td>Only available when the filter widget is active. This variable contains all external search inputs with <code>data-column="all"</code>, bound using the <ahref="#function-bind-search"><code>bindSearch</code></a> function.

A new <code>colgroup</code> with <code>col</code> elements is only added if:
<ul>
<li><ahref="#widthfixed"><code>widthFixed</code></a> is <code>true</code>.</li>
<li>A predefined <code>colgroup</code> element does not already exist in the table *.</li>
</ul>
* <spanclass="label label-info">Note</span> If a <code>colgroup</code> was added by the plugin, calling this function additional times will refresh the set widths<br>

Also, the <code>col</code> elements within the <code>colgroup</code> are set with a percentage width to dynamically maintain the fixed column width ratios.<br>
<li><code>getIt</code> - Boolean flag (optional if <code>false</code>).</li>
</ul>
When calling the function, to get a tbody, set the <code>getIt</code> boolean parameter to <code>true</code> and the removed tbody is returned; setting this option to <code>false</code> or optionally not including it will restore the tbody.
<br>
Here is a basic example of how this function is used:
Please note that completely detaching the tbody was found to be a much quicker method of manipulating DOM elements than just hiding the tbody; this is especially true in older browsers.
When calling the function, set the <code>toggle</code> option to add (<code>true</code>) or remove (<code>false</code>) process indicators. Include any specific header cells within the <code>$ths</code> variable with which to add the process indicator. When <code>$ths</code> is not defined and a sort is applied, the currently sorted header cells will show process indicators.<br>
<br>
All this function does is add or remove a class name of <code>"tablesorter-processing"</code> and the class name contained within the <ahref="#cssprocessing"><code>cssProcessing</code> option</a>.<br>
<br>
Here is a basic example of how this function is used:
Please note that currently the processing icons do not animate (see <ahref="https://github.com/Mottie/tablesorter/issues/158">issue #158</a>). This is due to javascript being a single-threaded, meaning it only does one task at a time, and maximizing the sorting script. So lots of processing is needed to sort & rebuild the table and thus it has no time for animation. If someone knows of a better solution, please share!
<li><code>table</code> - table DOM element (or jQuery object) of table.</li>
</ul>
Please note that this function uses jQuery <code>empty()</code>. All data & event handlers are removed. No where within the tablesorter script or included widgets is this function used, it is left intact for backwards compatibility.
This function allows you to bind the same header event listeners to external headers cells (usually clones of the original table). This includes the triggered <code>sort</code> event, left click (only) to sort, ignoring long clicks (> 250ms), pressing enter to trigger a sort (must have focus and a <code>tabindex</code> attribute) and cancelling selection of text (if the option is set).<br>
<br>
To ensure the columns match the original table, include <code>data-column</code> attributes pointing to the desired column.<br>
<br>
Here is a basic example of how this function is used:
In <spanclass="version">v2.16.2</span>, this function now saves all extra (external) headers to the <ahref="#variable-extra-headers"><code>config.$extraHeaders</code></a> variable which allows the plugin to automatically update the sort status.
The original header cell content is saved, within the <ahref="#variable-headercontent"><code>headerContent</code></a> variable array, before the <ahref="#headertemplate"><code>headerTemplate</code></a> is applied and before the <ahref="#onrendertemplate"><code>onRenderTemplate</code></a> and <ahref="#onrenderheader"><code>onRenderHeader</code></a> callbacks are executed.<br>
<li><code>table</code> - table DOM element (or jQuery object) of table.</li>
</ul>
Please note that only header cells that still contain a div with a class name of <code>tablesorter-header-inner</code> will have their contents restored; it assumes that the contents have already been restored.
<li><code>callback</code> - Function executed once tablesorter has been removed.</li>
</ul>
When calling the function, set the <code>removeClasses</code> option to <code>true</code> to include removing of the <code>"tablesorter"</code> class name, tablesorter theme name (e.g. <code>"tablesorter-blue"</code>) and the class name applied by the <ahref="#tableclass"><code>tableClass</code> option</a>. The callback function only provides a <code>table</code> (DOM element only) parameter.<br>
<br>
Here is a basic example of how this function is used:
alert('tablesorter has been removed! No sort for you!');
});</pre>
Please note that only header cells that still contain a div with a class name of <code>tablesorter-header-inner</code> will have their contents restored; it assumes that the contents have already been restored.
This function is used when the <ahref="#sortlocalecompare"><code>sortLocaleCompare</code></a> option is set to <code>true</code>. Please refer to the option and <ahref="example-locale-sort.html">the demo</a> for more details on the defaults values and how to add more accented characters.
<td>This function returns a zero-based index value of the position of the value within the array, otherwise it returns -1 (Modified <spanclass="version updated">v2.15.6</span>).
<li><code>value</code> - value to find within the array.</li>
<li><code>array</code> - array (sortList) to search for the value.</li>
</ul>
Sadly, this function has limited usefulness outside of tablesorter. It is only meant to search a <code>sortList</code> array and determine if a column (value) is already contained within it. Here is a basic example of how this function is used:
After <spanclass="version">v2.15.6</span>, this function returns a zero-based index of the position of the value within the array parameter, or -1 if the value is not in the array. Previously, this function returned a boolean value of <code>true</code> if the value was contained within the array, or <code>false</code> if not.
The <code>myParser</code> object must contain a proper template. The template must include an <code>id</code>, <code>is</code>, <code>format</code> and <code>type</code> blocks. Please refer to the <ahref="example-parsers.html">writing custom parsers</a> demo page for more details & an example.
<li><code>methods</code> - an object containing methods to be added, indexed by method names. These methods can use config object by refering <code>this</code>.</li>
<li><code>table</code> - table element or jQuery object of the selected table.</li>
<li><code>'mywidget'</code> - ID of the widget to check.</li>
</ul>
This function returns a <code>boolean</code> value, where <code>true</code> means the widget is currently installed and active; and <code>false</code> means the widget is not installed.<br>
In <spanclass="version updated">v2.19.0</span>, a <code>"refreshing"</code> parameter was added to the <code>remove</code> widget function to indicate that the widget will be refreshed so it will only be temporarily removed (see <ahref="example-widgets.html">this demo</a> for more details).<br>
The <code>myWidget</code> object must contain a proper template. The template must include an <code>id</code> and <code>format</code> blocks. The <code>priority</code>, <code>options</code>, <code>init</code> and <code>remove</code> blocks are optional.<br>
<br>
Please refer to the <ahref="example-widgets.html">writing custom widgets</a> demo page for more details & an example.
<td>This function applys (refreshes) all currently selected widgets on a table (<spanclass="version updated">v2.16.0</span>; <spanclass="version updated">v2.19.0</span>).
<li><code>callback</code> - optional, a function executed after all widgets have been applied; the only parameter is <code>table</code> (<spanclass="version">v2.19.0</span>).</li>
The <code>init</code> flag is only set to <code>true</code> to extend the default option values from the widget options block. If the widget(s) have already been applied to the table, just leave this parameter undefined.<br>
<br>
This function is called when the <ahref="#applywidgets">applyWidgets</a> method is triggered.
In <spanclass="version updated">v2.19.0</span>, this function was modified to internally use the <ahref="#function-removewidget">removeWidget</a> function & a <ahref="#refreshcomplete"><code>"refreshComplete"</code></a> event is now triggered upon completion.<br>
The <code>doAll</code> flag is set to <code>true</code> if all widgets contained with the global <ahref="#variable-widgets"><code>$.tablesorter.widgets</code></a> array are to be removed.<br>
When <code>doAll</code> is <code>false</code>, only widgets <em>not contained</em> within the <code>config.widget</code> option are removed; then if the <code>dontapply</code> flag is <code>false</code>, the widgets named in that option are reapplied (without removing them).<br>
<li><code>names</code> - string (space or comma separated widget names), an array of widget names, or if <code>true</code> all installed widgets are removed.</li>
<li><code>refreshing</code> - if <code>true</code>, the widget name will not be removed from the <ahref="#widgets"><code>widgets</code></a> option; any other setting and the name will be removed.</li>
<li><code>table</code> - table DOM element (or jQuery object).</li>
<li><code>object</code> - object containing zero-based column indexes or column class names as a key (e.g. <code>table.config.headers</code> or <code>table.config.widgetOptions.filter_functions</code>; any data found as the value (of the <code>key : value</code> pair) will be returned.</li>
<li><code>key</code> - key to be Object key; this can be a zero-based column index or header class name/id.</li>
</ul>
As a full example, say you have a header cell with a class name of <code>"event"</code>. And you want to use the <code>textExtraction</code> function for that column, then you would use this function as follows:
The <code>".event"</code> key can be replaced with a zero-based column index, if the <code>textExtraction</code> option is set up using indexes.
This function is sometimes used in conjunction with the <code>getData</code> function. This function is called first because the getData function uses the result in the <code>configHeaders</code> parameter - the <code>config.headers</code> option result from this function would be an object and not a function.
<td>This functions gets the sorter, string, empty, etc options for each column from jQuery data, metadata, header option or header class name ("sorter-false") (v2.1.16).
<li><code>configHeaders</code> - table.config.headers option for the current column.</li>
<li><code>key</code> - get value for this option name, e.g. "sorter".</li>
</ul>
If the value of the "sorter" option is needed for a column, set the <code>key</code> to "sorter" and this function will return the set value, e.g. <code>false</code>, <code>digit</code>, <code>currency</code> etc.<br>
If <code>table</code> is not provided, the format float function will default to U.S. number formatting. The reason a <code>table</code> parameter is needed is to check the value of the <ahref="#usnumberformat"><code>usNumberFormat</code></a> option.<br>
This function uses the <ahref="#usnumberformat"><code>usNumberFormat</code></a> option to determine if either commas or decimals are removed before converting the value within the <code>string</code> parameter into a number type variable. This function does not use the <ahref="#function-isdigit"><code>$.tablesorter.isDigit</code></a> function.<br>
Any numbers wrapped within parentheses are converted into negative numbers; but any other symbols (e.g. currency) are not removed and will cause this function to determine the string as a non-number (e.g. "$1.25" will be returned as a string).<br>
<li><code>string</code> - a string possibly containing a number.</li>
</ul>
This function will return a boolean value of <code>true</code> if the <code>string</code> parameter contains a number after all commas, decimals, quotes and spaces are removed, and still allow plus or minus signs, or the number wrapped in parenthesis (negative values).<br>
<br>
Use this function as follows:
<preclass="prettyprint lang-js">// boolean value of true returned
This function is ONLY included within the <code>widget-pager.js</code> and <code>jquery.tablesorter.pager.js</code> files; in version 3+, I plan to add it as a selectable option in a build.<br>
This function will add a table row to the thead, with a class name from either the pager plugin <code>cssErrorRow</code> option setting, or the pager widget <code>pager_css.errorRow</code> option (the default class name is <code>"tablesorter-errorRow"</code>; and styled within each theme css file).<br>
When passing this function a message, there are three possibilities:
<ol>
<li>Plain string - <code>"table refuses to cooperate"</code></li>
<li>HTML row string - <code>'<tr><td colspan="' + table.config.columns + '">yeah, instead of showing your data... I am taking a nap</td></tr>'</code> (the <ahref="#variable-columns"><code>table.config.columns</code> variable</a> contains the number of table columns; use as needed)</li>
<li>undefined - completely leave out a message parameter <code>$.tablesorter.showError( table );</code> to remove all error rows from the table thead.</li>
<li><code>table</code> - table DOM element (or jQuery object) of table.</li>
<li><code>$els</code> - jQuery object of all input (search) elements to bind.</li>
<li><code>false</code> - boolean flag to force a new search.</li>
</ul>
The external elements (<code>$els</code>) will allow searching the table using "search" and "keyup" events (enter to start & escape to cancel the search), and uses the <ahref="#widget-filter-livesearch"><code>filter_liveSearch</code></a> option, or delayed search.<br>
<br>
Include a <code>data-column="#"</code> attribute (where <code>#</code> is the column number) in the search input, to specify to which column the search should apply ~ see <ahref="example-widget-filter-external-inputs.html">this demo</a> for a full example. <spanclass="label label-warning">Warning!</span>, if no <code>data-column</code> attribute is added to the input, the input will be ignored.<br>
<br>
In <spanclass="version">v2.15</span>, use a <code>data-column="all"</code> to bind an external any-match search filter; but note that adding an external any-match filter using this method will not override the filter set by the <ahref="#widget-filter-external"><code>filter_external</code></a> option.<br>
<br>
The third function parameter, <code>false</code>, is optional. When set to <code>false</code> it forces the inputs to update their values (same as setting the <code>apply</code> flag when using the <ahref="#function-setfilters"><code>setFilters</code></a> function), and reapplies (forces) the current search to be applied again, even if the filter values have not changed; this allows changing the data column attribute dynamically. See the <ahref="example-widget-filter-external-inputs.html">filter external inputs demo</a> for an example.<br>
<br>
<spanclass="label label-warning">Warning!</span> If the third parameter is set to <code>true</code> the saved internal filters (<ahref="#variable-filters"><code>config.$filters</code></a>) will be replaced - not recommended!
<td>This filter widget function allows the updating or replacing of filter select options from an external source. (<spanclass="version">v2.17.5</span>):

</ul>
Use this function as follows:<br>
<preclass="prettyprint lang-js">// replace filter select options for the first column with 1,2,3,4

This function returns an array of filter values (e.g. <code>[ '', '', '', '', '', '2?%' ]</code>), or <code>false</code> if the selected table does not have a filter row. It will also return an additional parameter if an external input with <code>data-column="all"</code> containing the value used when matching any table column.<br>
In <spanclass="version updated">v2.15</span>, this function will also return values from any external filters (set either by the <ahref="#filter-external"><code>filter_external</code> option</a> or using the <ahref="#function-bindsearch"><code>bindSearch</code> function</a>) - with or without an internal filter row.<br>
If the second parameter is set to <code>true</code>, it forces the function to get all of the current filter values directly from the inputs. Otherwise, by default, the function returns the last search as found in this stored data <code>$('table').data('lastSearch');</code>.
<td>This filter widget function allows setting of the filters; include a <code>true</code> boolean to actually apply the search (<spanclass="version">v2.9</span>; <spanclass="version updated">v2.16</span>):
<li><code>table</code> - table DOM element (or jQuery object) of table.</li>
<li><code>filter</code> - array of filter values to apply to the table.</li>
<li><code>apply</code> - boolean flag, if <code>false</code> (default setting), the input values are updated, but not searched for within the table.</li>
</ul>
Use this function as follows:<br>
<preclass="prettyprint lang-js">// update filters, but don't apply the search
As of <spanclass="version updated">v2.15</span>, this function will also set values in any external filters (set either by the <ahref="#filter-external"><code>filter_external</code> option</a> or using the <ahref="#function-bindsearch"><code>bindSearch</code> function</a>). An additional search parameter can be included to match any column, but please include an external input with <code>data-column="all"</code> using the <code>bindSearch</code> function so your users will know that a search has been applied.<br>
Also, changed is that when a <code>true</code> value is passed as a third parameter, the search is forced to refresh on the table; otherwise, if the filters set in the search exactly match the previous search, it would be ignored - this was added to prevent numerous ajax calls with exactly the same search or sort parameters (when using the pager).
<td>This resizable widget function allows resetting column width changes and clearing out the saved set widths (<spanclass="version">v2.4</span>; <spanclass="version updated">v2.15</span>)
<td>Added a <code>resize</code> event to the table headers - used by the stickyHeaders widget, but this is a public function available to any widget (<spanclass="version">v2.10</span>).
<divclass="collapsible"><br>
There is no built-in resize event for non-window elements, so when this function is active it triggers a <code>resize</code> event when the header cell changes size. So, if you are writing your own widget and need a header <code>resize</code> event, just include the <code>jquery.tablesorter.widgets.js</code> file, or just the extract the function from that file.<br>
<li><code>table</code> - table DOM element (or jQuery object) of table.</li>
<li><code>key</code> - name of the variable to save</li>
<li><code>value</code> - value of the variable that is saved (for saving only); set to <code>null</code> if wanting to get a value with options.</li>
<li><code>options</code> - storage options; see below</li>
</ul>
This function attempts to give every table a unique identifier using both the page url and table id (or index on the page if no id exists), by default. Here is a usage example and a look at what is stored within the local storage:
// stored as, test = : {"/tablesorter/docs/":{"tablesorter-demo":"123"}}
</pre>
The saved table url & id can be overridden by setting table data attributes <code>data-table-page</code> (url) and <code>data-table-group</code> (id), as in this sample markup:
To change the default data attributes, use the <code>options</code> to modify them as follows:<preclass="prettyprint lang-js">$.tablesorter.storage( table, key, value, {
// table id/group id
id : 'group1',
// this group option sets name of the table attribute with the ID;
// but the value within this data attribute is overridden by the above id option
group: 'data-table-group'
// table pages
url : 'page1',
// this page option sets name of the table attribute with the page/url;
// but the value within the data attribute is overridden by the above url option
page: 'data-table-page'
});</pre>
The priority of table ID settings is as follows:
<ol>
<li><code>options.id</code> setting</li>
<li>Table data attribute (<code>data-table-group</code> by default) value</li>
<li>Table id</li>
<li>Index of the table on the page</li>
</ol>
The priority of table url (group) settings is as follows:
<ol>
<li><code>options.url</code> setting</li>
<li>Table data attribute (<code>data-table-page</code> by default) value</li>
The <ahref="#fixedurl"><code>fixedUrl</code></a> option allows you to override the current page url (it doesn't need to be a url, just some constant value) and save data for multiple tables across a domain. The value from this option has a lower priority than the <code>options</code> id or group settings (see priority list above).<br>
<br>
When using the storage utility to <em>get</em> a value <em>and</em> use custom table options, set the <code>value</code> parameter to <code>null</code>.<br>
<br>
Lastly, this storage utility function needs the <code>parseJSON</code> function available in jQuery v1.4.1+.
