<ul>
|
|
<li>In <span class="version">v2.25.0</span>
|
|
<ul>
|
|
<li><code>math_rowFilter</code> can now be overridden by the row's <code>data-math-filter</code> attribute.</li>
|
|
<li>
|
|
Lots of optimizations!
|
|
<ul>
|
|
<li>On initialization, only tbody cells with a <code>rowspan</code> or <code>colspan</code> are now processed and only get a "data-column" set if the internal <code>cellIndex</code> doesn't match the calculated cell index.</li>
|
|
<li>Initial calculation is no longer performed three times in a row</li>
|
|
<li>The cache is now only updated if cell content inside of a sortable tbody was modified.</li>
|
|
<li>These changes should improve performance and reduce lag after initialization and updating the table (see <a href="https://github.com/Mottie/tablesorter/issues/1048">issue #1048</a>.</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
</li>
|
|
<li>In <span class="version">v2.24.6</span>, added <code>math_rowFilter</code> option.</li>
|
|
<li>In <span class="version">v2.24.0</span>
|
|
<ul>
|
|
<li>Added "below" type of data-gathering (see <a href="#attribute_settings">Attribute Settings</a> below for more info). See <a href="https://github.com/Mottie/tablesorter/pull/1027">pull #873</a>; thanks to <a href="https://github.com/LvLynx">LvLynx</a>!.</li>
|
|
<li>Added <code>math_none</code> option which allows customizing the text added to a cell when there are no matching math elements (.</li>

|
|
<ul>
|
|
<li>In <span class="version updated">v2.22.0</span>,
|
|
<ul>
|
|
<li>Fixed an issue with a sum column encountering a cell without a defined "data-math" attribute returning an empty string instead of zero. See <a href="https://github.com/Mottie/tablesorter/issues/873">issue #873</a>.</li>
|
|
<li>Fixed a javascript error occurring on empty tables & now all updates will reapply column indexing to tbody cells - I know this isn't ideal as it would be slow on larger tables.</li>
|
|
</ul>
|
|
</li>
|
|
<li>In <span class="version">v2.19.1</span>, added <code>math_event</code> option & fixed an issue with event unbinding in jQuery version < 1.9.</li>
|
|
<li>In <span class="version">v2.17.1</span>,
|
|
<ul>
|
|
<li>Values added to the data-attribute set by the <a href="../#textattribute"><code>textAttribute</code> option</a> will now be used in the calculation instead of the actual cell content.</li>
|
|
<li>The Grand Total cells now shows a higher precision value to emphasize this point.</li>
|
|
</ul>
|
|
</li>
|
|
<li>In <span class="version">v2.16.4</span>, added:
|
|
<ul>
|
|
<li>Two new options: <code>math_prefix</code> and <code>math_suffix</code>, which will be added before or after the prefix or suffix, respectively.</li>
|
|
<li>Added "Mask Examples" section with examples, and how to use the <code>$.tablesorter.formatMask</code> function.</li>

</ul>

|
|
<ul>
|
|
<li>This widget will <strong>only work</strong> in tablesorter version 2.16+ and jQuery version 1.7+.</li>
|
|
<li>It adds basic math capabilities. A full list of default formulas is listed in the "Attribute Settings" section.</li>
|
|
<li>Add your own custom formulas which manipulating an array of values gathered from the table by row, column or a column block (above).</li>
|
|
<li>This is by no means a comprehensive widget that performs like a spreadsheet, but you can customize the data gathering "type" and available "formula", as desired.</li>
|
|
<li>The widget will update the calculations based on filtered rows, and will update if any data within the table changes (using update events).</li>
|
|
<li>This widget is not optimized for very large tables, for two reasons:
|
|
<ul>
|
|
<li>On initialization, it cycles through every table row, calculates the column index <del>, and adds a <code>data-column</code> attribute</del> (Fixed in <span class="version updated">v2.25.0</span>).</li>
|
|
<li>It uses the update method whenever it recalculates values to make the results sortable. This occurs when any of the update methods are used and after the table is filtered.</li>
|
|
</ul>
|
|
</li>
|
|
<li>When setting tablesorter's <code>debug</code> option to <code>true</code>, this widget will output each <code>{type}-{formula}</code> value found, the array of numbers used and the result.</li>

<h3>Javascript-number-formatter details</h3>
|
|
<h3>Features</h3>
|
|
<ul>
|
|
<li>Short, fast, flexible yet standalone. Only 75 lines including MIT license info, blank lines & comments.</li>
|
|
<li>Accept standard number formatting like <code>#,##0.00</code> or with negation <code>-000.####</code>.</li>
|
|
<li>Accept any country format like <code># ##0,00</code>, <code>#,###.##</code>, <code>#'###.##</code> or any type of non-numbering symbol.</li>
|
|
<li>Accept any numbers of digit grouping. <code>#,##,#0.000</code> or <code>#,###0.##</code> are all valid.</li>
|
|
<li>Accept any redundant/fool-proof formatting. <code>##,###,##.#</code> or <code>0#,#00#.###0#</code> are all OK.</li>
|
|
<li>Auto number rounding.</li>
|
|
<li>Include a prefix & suffix with the mask</li>
|
|
<li>Simple interface, just supply mask & value like this: <code>$.tablesorter.formatMask( "0.0000", 3.141592, "prefix ", " suffix" );</code>
|
|
<pre class="prettyprint lang-js">$.tablesorter.formatMask( "$ 0.0000 USD", 1234.567, "prefix ", " suffix" );
|
|
// prefix $ 1234.5670 USD suffix</pre>
|
|
</li>
|
|
</ul>
|
|
<h3>Limitation</h3>
|
|
<ul>
|
|
<li>No scientific/engineering formatting.</li>
|
|
<li>Not for date or phone formation.</li>
|
|
<li>No color control.</li>
|
|
<li><del>No prefix or suffix is allowed except leading negation symbol. So <code>$#,##0.00</code> or <code>#,###.##USD</code> will not yield expected outcome. Use <code>'$'+ $.tablesorter.formatMask('#,##0.00', 123.45)</code> or <code>$.tablesorter.formatMask('#,##0.00', 456.789) + 'USD'</code></del></li>
|
|
<li>The prefix or suffix can not include any numbers (<code>0-9</code>), hashes (<code>#</code>), dashes (<code>-</code>), or plus signs (<code>+</code>)</li>
|
|
</ul>
|
|
<h3>Note</h3>
|
|
<ul>
|
|
<li>When there's only one symbol is supplied, system will always treat the single symbol as Decimal. For instance, <code>$.tablesorter.formatMask( '#,###', 1234567.890)</code> will output <code>1234567,890</code>.</li>
|
|
<li>To force a single symbol as Separator, add a trailing dot to the end like this: <code>$.tablesorter.formatMask( '#,###.', 1234567.890)</code> which will then output <code>1,234,567</code>.</li>

<li><code>arry</code> - the array of values gathered by the widget.</li>
|
|
</ul>
|
|
In this function, if a anything is returned, it will be automatically added to the <code>$cell</code> as html. Or, return <code>false</code> and no change is made to the cell contents; use this method if you manipulate the <code>$cell</code> contents and don't want the widget to do it.<br>
|
|
<br>
|
|
If you need to format the data output after manipulating the <code>value</code>, you can use <code>wo.math_mask</code>, or a different mask, by using the <code>$.tablesorter.formatMask( mask, value );</code> function. For example:
|
|
<pre class="prettyprint lang-js">math_complete : function($cell, wo, result, value, arry){
|
|
var percent = Math.round( value * 1e4 ) / 100; // percent with two decimal places
|
|
return $.tablesorter.formatMask( wo.math_mask, percent ) + ' %';
|
|
}</pre>
|
|
More details can be found in the <code>math_mask</code> description.

<h3><a href="#">Attribute Settings</a></h3>
|
|
<div>
|
|
The math widget data-attibute setting requires two parts: type & formula
|
|
<pre class="prettyprint lang-html"><td data-math="{type}-{formula}"></td></pre>
|
|
When set, the data is gathered based on the math type ("row", "column", "above", "below" or "all") and passed to the formula as an array.
|
|
<h3><code>{type}</code> (data gathering)</h3>
|
|
<ul>
|
|
<li><code>row</code> - gather the table cell values from the same row as the <code>data-math</code> attribute.</li>
|
|
<li><code>above</code> - gather the table cell values from the same column as the <code>data-math</code> attribute, but stop when the first table cell is reached, or when another cell with a data-attribute with an "above" type is reached; see the first table demo below to see why this is useful.</li>
|
|
<li><code>below</code> (<span class="version">v2.24.0</span>) - gather the table cell values from the same column as the <code>data-math</code> attribute, but stop when the last table cell is reached, or when another cell with a data-attribute with a "below" type is reached.</li>
|
|
<li><code>col</code> - gather the table cell values from the same column as the <code>data-math</code> attribute.</li>
|
|
<li><code>all</code> - gather all table cell values with a data-math attribute that start with "all".</li>
|
|
</ul>
|
|
<h3><code>{formula}</code> (defaults)</h3>
|
|
<ul>
|
|
<li><code>count</code> - returns the count (length) of the data set.</li>
|
|
<li><code>sum</code> - returns the sum of all values in the data set.</li>
|
|
<li><code>max</code> - returns the maximum value in the data set.</li>
|
|
<li><code>min</code> - returns the minimum values in the data set.</li>
|
|
<li><code>mean</code> - returns the mean (average) of all values in the data set; it uses the <code>sum</code> formula in part of the calculation.</li>
|
|
<li><code>median</code> - returns the median (middle value) of the data set.</li>
|
|
<li><code>mode</code> - returns an array of the mode(s) (most frequent value or values) in the data set; an array is always returned, even if only one mode exists (see the second demo below).</li>
|
|
<li><code>range</code> - returns the range (highest minus lowest value) of the data set.</li>
|
|
<li><code>varp</code> - returns the variance of the data set (population).</li>
|
|
<li><code>vars</code> - returns the variance of the data set (sample).</li>
|
|
<li><code>stdevp</code> - returns the standard deviation of the data set (population).</li>
|
|
<li><code>stdevs</code> - returns the standard deviation of the data set (sample).</li>
|
|
<li><code>custom</code> (not a default)
|
|
<ul>
|
|
<li>Custom formulas can have any name</li>
|
|
<li>Return your result after making whatever calculation from the array of data passed to the formula</li>
|
|
<li>For example:
|
|
<pre class="prettyprint lang-js">// adding a custom equation... named "product"
|
|
// access from data-math="row-product" (or "above-product", "below-product" or "col-product")
|
|
// config parameter added v2.24.0 to allow access to table settings
|
|
$.tablesorter.equations['product'] = function(arry, config) {
|
|
// multiple all array values together
|
|
var product = 1;
|
|
$.each(arry, function(i,v){
|
|
// oops, we shouldn't have any zero values in the array
|
|
if (v !== 0) {
|
|
product *= v;
|
|
}
|
|
});
|
|
return product;
|
|
};</pre>
|
|
</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
<h4>Ignoring cells</h4>
|
|
<ul>
|
|
<li>Entire row: if the <code><tr></code> math data-attribute contains the keyword <code>"ignore"</code> then that entire row of cells will be skipped when building the array of data to be used for calculations.
|
|
<pre class="prettyprint lang-html"><tr data-math="ignore"><td>1</td><td>2</td><td>3</td></tr></pre>
|
|
</li>
|
|
<li>Cell: if the table cell math data-attribute contains the keyword <code>"ignore"</code> then that cell will be skipped when building the array of data to be used for calculations.
|
|
<pre class="prettyprint lang-html"><td data-math="ignore">1</td></pre>
|
|
</li>
|
|
<li>Column: set the widget <code>math_ignore</code> option with an array of zero-based column indexes of columns to ignore or skip when building the array of data for calculations.
|
|
<pre class="prettyprint lang-js">math_ignore : [0,1]</pre>
|

</ul>

<h3><a href="#">Mask Examples</a></h3>
|
|
<div>
|
|
The formatting function can be used separately from the math widget:
|
|
<pre class="prettyprint lang-js">// $.tablesorter.formatMask(mask, value, prefix, suffix);
|
|
$.tablesorter.formatMask('$#,##0.00 USD', 12345.678, 'prefix ', ' suffix');
|
|
// result: "prefix $12,345.68 USD suffix"</pre>
|
|
<ul>
|
|
<li>The <code>$.tablesorter.formatMask</code> function has the following parameters:
|
|
<ul>
|
|
<li><code>mask</code> - please refer to the <code>math_mask</code> option for more details.</li>
|
|
<li><code>value</code> - number to be formatted.</li>
|
|
<li><code>prefix</code> - please refer to the <code>math_prefix</code> option for more details (<span class="version updated">v2.16.4</span>).</li>
|
|
<li><code>suffix</code> - please refer to the <code>math_suffix</code> option for more details (<span class="version updated">v2.16.4</span>).</li>
