tablesorter is a jQuery plugin for turning a standard HTML table with THEAD and TBODY tags into a sortable table without page refreshes.
tablesorter can successfully parse and sort many types of data including linked data in a cell.

### Notice!

* Because of the change to the internal cache, the tablesorter v2.16+ core, filter widget and pager (both plugin & widget) will only work with the same version or newer files.

#### <a name="v2.16.3">Version 2.16.3</a> (4/30/2014)

* Docs:
  * Clean up of docs for the following widgets:
      * [Column selector widget](http://mottie.github.io/tablesorter/docs/example-widget-column-selector.html)
      * [Editable widget](http://mottie.github.io/tablesorter/docs/example-widget-editable.html)
      * [Grouping widget](http://mottie.github.io/tablesorter/docs/example-widget-grouping.html)
      * [Math widget](http://mottie.github.io/tablesorter/docs/example-widget-math.html)
      * [Select2 filterFormatter](http://mottie.github.io/tablesorter/docs/example-widget-filter-formatter-select2.html)
  * Update [`textSorter` option demo](http://mottie.github.io/tablesorter/docs/example-option-custom-sort.html) - the sorting the Icelandic alphabet using sugar's array sort now works properly.

* Core:
  * Fix `headers` option indexing of cells in multiple header rows
      * Setting an index in the multiple row header will now correctly set the column parser.
      * See [this demo](http://jsfiddle.net/Mottie/abkNM/2645/) - the 10th cell (zero-based index) in the header has the sorter set to "month".
  * Set processing icon to only show after 500ms, it will not show at all if the sort ends before then.
  * Check for jQuery's `closest` function and use it, or fall back to equivalent code (maintaining support for jQuery 1.2.6+). Fixes [issue #597](https://github.com/Mottie/tablesorter/issues/597).
  * Remove widget init delay added in v2.16.1-beta.

* Filter:
  * Remove old cached indexing:
      * It was causing already filtered rows to return an incorrect cached row value.
      * Fixes [issue #600](https://github.com/Mottie/tablesorter/issues/600) &amp; see this [Stackoverflow question](http://stackoverflow.com/q/23384787/145346).
  * Update check for "filter-parsed" class, because the `getData` function will only return the first class name starting with "filter-".
  * Filter select updates:
      * Add `filter-select-nosort` header class name to prevent select option sorting.
      * Filter select option sort now uses the assigned column parser to parse &amp; sort the options.
      * Filter select options are now sorted using the `textSorter` function, if set, and if not set, it falls back to natural sorting.
      * Fixes [issue #599](https://github.com/Mottie/tablesorter/issues/599).
      * Add note to ensure textSorter receives strings, or a javascript error occurs.
  * Select2 filterFormatter now allows setting of initial settings. Fixes [issue #598](https://github.com/Mottie/tablesorter/issues/598).

* Sticky Headers
  * Add support for `filter_hideFilters` set to `true`. See this [Stackoverflow question](http://stackoverflow.com/q/23342215/145346).

* Filter widget:
  * Search already filtered rows when not exactly matching content. Fixes [issue #593](https://github.com/Mottie/tablesorter/issues/593).

  * Add `stickyHeaders_filteredToTop` option. Fixes [issue #570](https://github.com/Mottie/tablesorter/issues/570).
* Input select parser: don't update columns with both sorter &amp; filter disabled. See [issue #570](https://github.com/Mottie/tablesorter/issues/570).

#### <a name="v2.16.1">Version 2.16.1</a> (4/24/2014)

* Core: 
  * Fixed an issue where ajax loaded data would cause a javascript error because of improper ignoring of data.

#### <a name="v2.16.0-beta">Version 2.16.0-beta</a> (4/20/2014)

* Doc & testing updates

  * Update to use Bootstrap 3.1.1.
  * Update to the latest testing files.
  * Reorganize example section &amp; cleanup.
  * Fix demos that include togglable parsed data.
  * Fix miscellaneous typos.

* Core
  * Make `computeColumnIndex` function public ([get details](http://mottie.github.io/tablesorter/docs/index.html#function-computecolumnindex)).
  * Move cache rows into the normalized data
      * This is a *big change*, as the cache rows no longer exist and did break several widgets.
      * This change allows for the Filter widget to better work with cached data (pager with `removeRows` set to `true`) & makes the sort tbodies widget possible.
      * Updated core tests.
  * Update `textExtraction` option
      * Default option is now `"basic"` and checks for a data-attribute (set by by the new `textAttribute` option).
      * Set this option to any string (besides an empty string) to revert back to the original method; this may be necessary in older versions of IE due to initialization speed issues.
      * Fixes [issue #154](https://github.com/Mottie/tablesorter/issues/154)
  * Add `textAttribute` option
      * It contains the data-attribute name which contains alternative table cell text.
      * This only applies to tbody table cells.
  * Add `sortReset` method callback (e.g. `$("table").trigger("sortReset", [callback]);`)
  * Update `applyWidgets` method to prevent being called numerous consecutive times.
  * Destroy method now clears the table cache & pager rows copy

* Parsers (extract date parsers)
  * "extractUSLongDate" - this parser finds a US long date anywhere in a table cell ([demo](http://jsfiddle.net/abkNM/2293/))
  * "extractMMDDYYYY" - this parser extracts dates in MMDDYYYY format ([demo](http://jsfiddle.net/Mottie/abkNM/2418/))
  * "extractDDMMYYYY" - this parser extracts dates in DDMMYYYY format ([demo](http://jsfiddle.net/Mottie/abkNM/2419/))

* Filter widget
  * Updated to use the new modified internal cache format.
       * Now usable with the pager with the `removeRows` option set to `true`.
       * Fixes [issue #515](https://github.com/Mottie/tablesorter/issues/515).
  * Add `filter_placeholder` global settings. Fixes [issue #582](https://github.com/Mottie/tablesorter/issues/582).
  * Add `filter_selectSource` option.
       * Allows add filter select options from an alternate source (e.g. ajax), or customizing options from the set column contents.
       * Fixes [issue #328](https://github.com/Mottie/tablesorter/issues/328).
  * Include `th`'s in the tbody.
  * Fix build select tbody indexing.
  * Filter reset (`filter_reset`) now accepts a jQuery object.

* Math widget
  * New [math widget demo](http://mottie.github.io/tablesorter/docs/example-widget-math.html) Replaces the previous alpha "Column sum widget" demo.
  * This widget adds basic math capabilities; by default the following functions are available: count, sum, max, min, mean, median, mode, range, variance (sample & population), standard deviation (sample & population).
  * Custom math functions can be added
  * Data from cells is gathered from the row, cells "above" the target cell, column, or the entire table.
  * More details are provided on the demo page.
  * Fixes [issue #136](https://github.com/Mottie/tablesorter/issues/136).

      * Any separator: comma (csv), tabs (tsv), spaces, etc
      * Javascript array
      * JSON

  * Works with the filter & pager widgets.
  * See [this demo](http://mottie.github.io/tablesorter/docs/example-widget-output.html) for more details.

  * Each tbody cell will display the header cell text when the table reflows.
  * See [this demo](http://mottie.github.io/tablesorter/docs/example-widget-reflow.html).
