tablesorter/README.md

tablesorter (FORK) 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="v2.21.3">Version 2.21.3</a> (3/26/2015)

* Core
  * Fix icon targeting for class names
  * Modified sort initiation method. A "click" event can now be triggered on a header to initiate a sort - [issue #849](https://github.com/Mottie/tablesorter/pull/849). Thanks [johnjameswhitman](https://github.com/johnjameswhitman).
  * General code cleanup; mostly changing `tagName` to `nodeName`.
  * Modified, then removed all references to `config.$extraTables` and `config.$extraHeaders` as it was causing a memory leak.
* Docs
  * Update jQuery to v1.11.2.
  * Update Bootstrap to v3.3.4.
* Grunt Build
  * Add custom build file name. See [issue #829](https://github.com/Mottie/tablesorter/issues/829).
  * The default custom build file name is now "jquery.tablesorter.custom-widgets.js".
  * See the [Customize wiki page](https://github.com/Mottie/tablesorter/wiki/Customize#custom-build) for more details.
* Filter
  * Make "disabled" a modifiable class name - modify it in `$.tablesorter.css.filterDisabled`.
  * Select2 filter formatter now escapes forward slashes.
* Output:
  * Minor code tweak.
* Pager:
  * Make `pagerUpdate` method page parameter optional. It was previously required or the page would reset to `0`.
  * Remove "refreshComplete" bind on destroy. Fixes [issue #854](https://github.com/Mottie/tablesorter/issues/854).
* Resizable:
  * Major overhaul of this widget to now make it compatible with the stickyHeaders widget.
  * Sadly, it still doesn't work properly with the updated scroller widget; it's on my to-do list!
* Scroller:
  * Added fixed column support! Fixes issues [#135](https://github.com/Mottie/tablesorter/issues/135), [#689](https://github.com/Mottie/tablesorter/issues/689), [#763](https://github.com/Mottie/tablesorter/issues/763) and [https://github.com/Mottie/tablesorter/issues/804](#804).
  * Check out the third table in the [scroller widget demo](http://mottie.github.io/tablesorter/docs/example-widget-scroller.html#group) - change the slider to adjust the number of fixed columns.
* Storage:
  * Add option (`widgetOptions.storage_useSessionStorage`) to allow switching from local to session storage. Fixes [#851](https://github.com/Mottie/tablesorter/issues/851).
  * Add a bunch of other storage widget options including `storage_tableId`, `storage_group`, `storage_fixedUrl` and `storage_page`. See the [documentation on how they might be useful](http://mottie.github.io/tablesorter/docs/#widget-storage-fixed-url).
  * Deprecated `config.fixedUrl` in favor of the `widgetOptions.storage_fixedUrl` option.
* Themes
  * Add "hover" class to all hover definitions (for the scroller widget mostly).
  * Remove filter element offsetting margins.
  * Target `background-color` instead of `background`. Fixes [issue #853](https://github.com/Mottie/tablesorter/issues/853).

#### <a name="v2.21.2">Version 2.21.2</a> (3/13/2015)

* Core: get accurate column count. Fixes [issue #840](https://github.com/Mottie/tablesorter/issues/840).
* Docs
  * Update to use jQuery UI v1.11.4.
  * Add note about resizable widget needing a non-breaking space in an empty cell. Fixes [issue #844](https://github.com/Mottie/tablesorter/issues/844).
* Editable: fix editable not updating properly on update/pager complete.
* Filter: prevent error if `parseFilter` returns `NaN` - this depends on what custom parsers return.
* Output: change carriage returns & tabs to unicode equivalent so it works in Excel. Fixes [issue #845](https://github.com/Mottie/tablesorter/issues/845).
* Pager
  * Don't recalculate total rows/pages if using ajax.
  * Remove outdated pager.min file in the `addons` folder; it is now available in the `dist/js/extras` folder.
* Uitheme: add icon classes while using stickyHeaders. See [issue #842](https://github.com/Mottie/tablesorter/issues/842).
