Example from the blue theme:

.tablesorter-blue .tablesorter-headerAsc {
  background-color: #9fbfdf;
  background-image: url(black-asc.gif);
}

Example from the blue theme:

.tablesorter-blue .tablesorter-headerDesc {
  background-color: #8cb3d9;
  background-image: url(black-desc.gif);
}

Example from the blue theme:

.tablesorter-blue .tablesorter-header {
  background-color: #99bfe6;
  background-repeat: no-repeat;
  background-position: center right;
  padding: 4px 20px 4px 4px;
  white-space: normal;
  cursor: pointer;
}

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.

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 showProcessing option to false.

<tbody class="tablesorter-infoOnly">
  <tr>
    <th>The contents of this tbody</th>
  </tr>
  <tr>
    <td>will not be sorted</td>
  </tr>
</tbody>

NOTE! 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.

• "mmddyyyy" (default)
• "ddmmyyyy"
• "yyyymmdd"

$(function(){
  $("table").tablesorter({

    dateFormat : "mmddyyyy", // default date format

    // or to change the format for specific columns,
    // add the dateFormat to the headers option:
    headers: {
      0: { sorter: "shortDate" }, // "shortDate" with the default dateFormat above
      1: { sorter: "shortDate", dateFormat: "ddmmyyyy" }, // day first format
      2: { sorter: "shortDate", dateFormat: "yyyymmdd" }  // year first format
    }

  });
});

• jQuery data data-dateFormat="mmddyyyy".
• metadata class="{ dateFormat: 'mmddyyyy'}". This requires the metadata plugin.
• headers option headers : { 0 : { dateFormat : 'mmddyyyy' } }.
• header class name class="dateFormat-mmddyyyy".
• Overall dateFormat option.

• bottom - sort empty table cells to the bottom.
• top - sort empty table cells to the top.
• none or zero - sort empty table cells as if the cell has the value equal to zero.
• emptyMax - sort empty table cells as having a value greater than the max (more positive) value (v2.16.2).
• emptyMin - sort empty table cells as having a value greater than the min (more negative) value (v2.16.2).

• jQuery data data-empty="top".
• metadata class="{ empty: 'top'}". This requires the metadata plugin.
• headers option headers : { 0 : { empty : 'top' } }.
• header class name class="empty-top".
• Overall emptyTo option.

$(function(){
  $("table").tablesorter({
    headers: {

      // See example - Disable first header cell; parser false skips extracting content
      0: { sorter: false, parser: false },

      // See example 2: Sort column numerically & treat any text as if its value is:
      1: { sorter: "digit", empty:  "top" }, // zero; sort empty cells to the top
      2: { sorter: "digit", string: "max" }, // maximum positive value

1. sortForce forces the user to have this/these column(s) sorted first (null by default).
2. SortList is the initial sort order of the columns.
3. SortAppend is the default sort that is added to the end of the users sort selection (null by default).

$(function(){
  $("table").tablesorter({
    sortForce  : [[0,0]],        // Always sort first column first
    sortList   : [[1,0], [2,0]], // initial sort columns (2nd and 3rd)
    sortAppend : [[3,0]]         // Always add this sort on the end (4th column)
  });
});

• jQuery data data-sortInitialOrder="asc".
• metadata class="{ sortInitialOrder: 'asc'}". This requires the metadata plugin.
• headers option headers : { 0 : { sortInitialOrder : 'asc' } }.
• header class name class="sortInitialOrder-asc".
• Overall sortInitialOrder option.

• This option no longer switches the sort to use the String.localeCompare method.
• When this option is true, the text parsed from table cells will convert accented characters to their equivalent to allow the alphanumeric sort to properly sort.
• If false (default), any accented characters are treated as their value in the standard unicode order.
• The following characters are replaced for both upper and lower case (information obtained from sugar.js sorting equivalents table):
  • áàâãä replaced with a
  • ç replaced with c
  • éèêë replaced with e
  • íìİîï replaced with i
  • óòôõö replaced with o
  • úùûü replaced with u
  • ß replaced with S
• Please see the example page for instrcutions on how to modify the above equivalency table.
• If you would like to continue using the String.localeCompare method, then set the sortLocaleCompare option to false and use the new textSorter option as follows:

  $('table').tablesorter({
    textSorter: function(a,b) {
      return a.localeCompare(b);
    }
  });

NOTE! See the Language wiki page for language specific examples and how to extend the character equivalent tables seen in the sortLocaleCompare demo.

• "max" will treat any text in that column as a value greater than the max (more positive) value. Renamed from "max+".
• "min" will treat any text in that column as a value greater than the min (more negative) value. Renamed from "max-".
• "top" will always sort the text to the top of the column.
• "bottom" will always sort the text to the bottom of the column.
• "none" or "zero" will treat the text as if it has a value of zero.

• jQuery data data-string="top".
• metadata class="{ string: 'top'}". This requires the metadata plugin.
• headers option headers : { 0 : { string : 'top' } }.
• header class name class="string-top".
• Overall stringTo option.

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.

<td data-text="1">First repository</td>

textExtraction : {
    '.styled' : function(node, table, cellIndex) {
        return $(node).find('strong').text();
    }
}

• The default text extraction method has been renamed and updated to get data from a data-attribute (set by the textAttribute option).
• If you need to support older versions of IE, this may add a significant delay to the table initialization especially for large tables; in this case, set the textExtraction option to any name other than "basic".
• Also, this option can now be set using a data-attribute named "data-text-extraction" on the table.

var myTextExtraction = function(node, table, cellIndex){
  // extract data from markup and return it
  // originally: return node.childNodes[0].childNodes[0].innerHTML;
  return $(node).find('selector').text();
}
$(function(){
  $("#myTable").tablesorter( { textExtraction: myTextExtraction } );
});

Now if the text you are finding in the script above is say a number, then just include the headers 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 (1 because we are using a zero-based index). All other columns will ignore this textExtraction function.

Added table and cellIndex variables to the textExtraction function in version 2.1.2 (this is not part of the original plugin).

$(function(){
  $("table").tablesorter({
    textExtraction: {
      1: function(node, table, cellIndex) {
           return $(node).find("span:last").text();
      }
    },
    headers: {
      1: { sorter : "digit" }
    }
  });
});

• If a namesspace is not defined, a (hopefully) unique random namespace will be generated.
• If defined, any "non-word" characters (anything not "a-z", "0-9" or "_") within the namespace will be removed.
• Added or not, the namespace will be saved with a leading period (e.g. ".myuniquetableid")

$(function(){
  $("#mytable").tablesorter({
    // if table id = "mytable", this namespace is saved as ".mytable"
    namespace : $('#mytable')[0].id;
  });
});

$(function(){
  $("table").tablesorter({
    numberSorter : function(a, b, direction, maxColumnValue){
      // direction; true = ascending; false = descending
      // maxColumnValue = the maximum value of that column (ignoring its sign)
      return a - b;
    }
  });
});

$(function(){
  $("table").tablesorter({
    textSorter : naturalSort
  });
});

$(function(){

    // replace the OVERALL text sorter function
    textSorter: function(a, b, direction, columnIndex, table){
      // direction: true = ascending; false = descending
      // columnIndex: zero-based index of the current table column being sorted
      // table: table DOM element (access options by using table.config)
      return a.localeCompare(b);
    }
  });
});

        // table: table DOM element (access options by using table.config)
        return a > b ? 1 : (a < b ? -1 : 0);
      },

Use the "tablesorter-filter" option to add an extra css class name as follows:

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      // css class applied to the table row containing the filters & the inputs within that row
      // or [ "filter1", "filter2", "filter3", etc... ]
      filter_cssFilter : "tablesorter-filter"
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_external : '.search'
    }
  });
});

<input class="search" type="search" data-column="0" placeholder="Search first column">

<input class="search" type="search" data-column="all" placeholder="Search entire table">

filter_formatter : {
    ".col-value" : function($cell, indx){
      return $.tablesorter.filterFormatter.uiSpinner( $cell, indx, {
        ...
      });
    }
}

• To add the jQuery UI slider, follow this example:

  $(function(){
    $("table").tablesorter({
      widgets: ["filter"],
      widgetOptions : {
        filter_formatter : {
          // column index `0` or use a jQuery selector `"th:contains('Discount')"`
          0 : function($cell, indx){
            return $.tablesorter.filterFormatter.uiSpinner( $cell, indx, {
              value : 0,  // starting value
              min   : 0,  // minimum value
              max   : 50, // maximum value
              step  : 1,  // increment value by
              addToggle: true, // Add a toggle to enable/disable the control
              valueToHeader: false // add current slider value to the header cell
            });
          }
        }
      }
    });
  });

  Any of the other jQuery UI spinner widget options can also be included.
  
  
• Filter formatter functions include: "uiSpinner", "uiSlider", "uiRange" (uiSlider ranged), "uiDatepicker" (range only), "html5Number", "html5Range" and "html5Color".
• 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_functions : {
    ".col-date" : {
        "< 2004" : function (e, n, f, i) {
            return n < Date.UTC(2004, 0, 1); // < Jan 1 2004
        },
        ...
    }
}

• Make a sorted select dropdown list of all column contents. Repeated content will be combined.

  $(function(){
    $("table").tablesorter({
      widgets: ["filter"],
      widgetOptions: {
        filter_functions: {
          // Add select menu to this column
          // set the column value to true, and/or add "filter-select" class name to header
          0 : true
        }
      }
    });
  });

  Alternately, instead of setting the column filter funtion to true, give the column header a class name of "filter-select". See the demo.
  
  
• 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.

  Regex example

  $(function(){
    $("table").tablesorter({
      widgets: ["filter"],
      widgetOptions: {
        // function variables:
        // e = exact text from cell
        // n = normalized value returned by the column parser
        // f = search filter input value
        // i = column index
        filter_functions: {
          // Add these options to the select dropdown (regex example)
          2 : {
            "A - D" : function(e, n, f, i) { return /^[A-D]/.test(e); },
            "E - H" : function(e, n, f, i) { return /^[E-H]/.test(e); },
            "I - L" : function(e, n, f, i) { return /^[I-L]/.test(e); },
            "M - P" : function(e, n, f, i) { return /^[M-P]/.test(e); },
            "Q - T" : function(e, n, f, i) { return /^[Q-T]/.test(e); },
            "U - X" : function(e, n, f, i) { return /^[U-X]/.test(e); },
            "Y - Z" : function(e, n, f, i) { return /^[Y-Z]/.test(e); }
          }
        }
      }
    });
  });

  Comparison example

  $(function(){
    $("table").tablesorter({
      widgets: ["filter"],
      widgetOptions: {
        // function variables:
        // e = exact text from cell
        // n = normalized value returned by the column parser
        // f = search filter input value
        // i = column index
        filter_functions: {
          // Add these options to the select dropdown (numerical comparison example)
          // Note that only the normalized (n) value will contain numerical data
          // If you use the exact text, you'll need to parse it (parseFloat or parseInt)
          4 : {
            "< $10"      : function(e, n, f, i) { return n < 10; },
            "$10 - $100" : function(e, n, f, i) { return n >= 10 && n <=100; },
            "> $100"     : function(e, n, f, i) { return n > 100; }
          }
        }
      }
    });
  });

  Note: if the filter_ignoreCase option is true, it DOES alter the normalized value (n) by making it all lower case.
  
  
• Make a custom filter for the column.

  $(function(){
    $("table").tablesorter({
      widgets: ["filter"],
      widgetOptions: {
        // function variables:
        // e = exact text from cell
        // n = normalized value returned by the column parser
        // f = search filter input value
        // i = column index
        filter_functions: {
          // Exact match only
          1 : function(e, n, f, i) {
            return e === f;
          }
        }
      }
    });
  });

  Note: if the filter_ignoreCase option is true, it DOES alter the normalized value (n) by making it all lower case.
  
  

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_hideEmpty : false
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_hideFilters : true
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_ignoreCase : false
    }
  });
});

• Header cell data (table.config.$headers.eq(0).data('placeholder', 'search for...');
• Header cell data-attribute (<th data-placeholder="Find Rank...">Rank</th>)
• Global filter_placeholder.search setting.

filter_placeholder : {
	search : '',
	select : '',
	from   : '', // datepicker range "from" placeholder
	to     : ''  // datepicker range "to" placeholder
}

When this option points to a reset element using a jQuery selector string, it is bound using event delegation. 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.

For example, add this button (<button class="reset">Reset</button>) 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):

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_reset : '.reset'
    }
  });
});

$.tablesorter.storage( $('table'), 'tablesorter-filters', '' );

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_searchDelay : 500
    }
  });
});

// target the first filter input
// this method will begin the search after the searchDelay time
$('input.tablesorter-filter:eq(0)').trigger('search');

// this method will begin the search immediately
$('input.tablesorter-filter:eq(0)').trigger('search', false);

// refresh the widget filter; no delay
$('table').trigger('search', false);

• The last search (for all columns) was not completely empty - all rows will be searched anyway.
• 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).
• If the search does not contain a logical or ( or or |), or a range delimiter ( - or to ) within the search query.
• If the search is not looking for an exact match (" or =) or a logical not search (!).
• Or, if the search is using a select dropdown without a "filter-match" class name (looking for an exact match).
• If the search does not contain an operator greater than or equal to a negative number (>=-10) or less than or equal to a positive number (<=10).
• And lastly, only search filtered rows if all rows are not hidden.

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_searchFiltered : false
    }
  });
});

filter_selectSource : {
    ".model-number" : [ "abc", "def", "ghi", "xyz" ]
}

• null - this value will set the default behavior and return all table cell values from the current column.
• An overall function - when this option is a function, it will be used for all filter selects in the table.

  $(function(){
    $("table").tablesorter({
      widgets: ["filter"],
      widgetOptions : {
        filter_selectSource : function(table, column, onlyAvail){
          // get an array of all table cell contents for a table column
          var array = $.tablesorter.filter.getOptions(table, column, onlyAvail);
          // manipulate the array as desired, then return it
          return array;
        }
      }
    });
  });

• An object containing column keys set with a function - when the option is set in this manner, a function can be applied to a specific column

  $(function(){
    $("table").tablesorter({
      widgets: ["filter"],
      widgetOptions : {
        filter_selectSource : {
          0 : function(table, column, onlyAvail){
            return $.getJSON('ajax/options.json', function(data) {
              // return false if there is a problem and the select
              // will display the original defaults
              return data.hasOwnProperty('options') ? data.options : false;
          }
        }
      }
    });
  });

• table - table DOM element
• column - zero-based index of the column with a filter select
• onlyAvail - boolean indicating if the returned options should only be from available (non-filtered) rows.

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_serversideFiltering : true
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_startsWith : true
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_useParsedData : false
    }
  });
});

• To only use parsed data in specific columns, set this option to false and use any of the following (they all do the same thing), set in order of priority:
  • jQuery data data-filter="parsed".
  • metadata class="{ filter: 'parsed'}". This requires the metadata plugin.
  • headers option headers : { 0 : { filter : 'parsed' } }.
  • header class name class="filter-parsed".
• Remember that parsed data most likely doesn't match the actual table cell text, 20% becomes 20 and Jan 1, 2013 12:01 AM becomes 1357020060000.

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_defaultAttrib : 'data-value'
    }
  });
});

<th data-value="<30">Age</th>

Previously, this option contained the class name to be applied to the sticky header row (tr) (v2.1).

Use the "stickyHeaders" option to add an extra css class name as follows:

$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // css class name applied to the sticky header
      stickyHeaders : "tablesorter-stickyHeader"
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // cloned table id suffix
      stickyHeaders_cloneId : "-clone"
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // cloned table id suffix
      stickyHeaders_includeCaption : false
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // Where to attach the stickyHeaders
      stickyHeaders_attachTo : '.wrapper' // $('.wrapper') jQuery object can also be used
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // apply sticky header top 30px below the top of the browser window
      stickyHeaders_offset : 30
    }
  });
});

stickyHeaders_offset : '.navbar-fixed-top' // jQuery selector string

stickyHeaders_offset : $('.navbar-fixed-top') // jQuery object

$(function(){
  $("table").tablesorter({
    widgets: ["resizable"],
    widgetOptions : {
      // add header resize detection
      stickyHeaders_addResizeEvent : true
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // The zIndex of the stickyHeaders, allows the user to adjust this to their needs
      stickyHeaders_zIndex : 100
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["resizable"],
    widgetOptions : {
      // css class name applied to the sticky header
      resizable : false
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["resizable"],
    widgetOptions : {
      // css class name applied to the sticky header
      resizable_addlastcolumn : true
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["resizable"],
    widgetOptions : {
      // headers widths applied at initialization & resizable reset
      // this setting includes any non-resizable cells (resizable-false)
      resizable_widths : [ '10%', '10%', '50px' ]
    }
  });
});

$(function(){
  $("table").tablesorter({
    widgets: ["saveSort"],
    widgetOptions : {
      // if false, the sort will not be saved for next page reload
      saveSort : false
    }
  });
});

To modify the class names used, extend from the $.tablesorter.themes variable as follows:

// Extend the themes to change any of the default class names ** NEW **
$.extend($.tablesorter.themes.jui, {
