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. This forked version adds lots of new enhancements including: alphanumeric sorting, pager callback functons, multiple widgets providing column styling, ui theme application, sticky headers, column filters and resizer, as well as extended documentation with a lot more demos.

### 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.

### [Documentation](//mottie.github.io/tablesorter/docs/)

* See the [full documentation](//mottie.github.io/tablesorter/docs/).
* All of the [original document pages](//tablesorter.com/docs/) have been included.
* Information from my blog post on [undocumented options](//wowmotty.blogspot.com/2011/06/jquery-tablesorter-missing-docs.html) and lots of new demos have also been included.
* Change log moved from included text file into the [wiki documentation](//github.com/Mottie/tablesorter/wiki/Changes).

### Demos

* [Basic alpha-numeric sort Demo](//mottie.github.com/tablesorter/).
* Links to demo pages can be found within the main [documentation](//mottie.github.io/tablesorter/docs/).
* More demos & playgrounds - updated in the [wiki pages](//github.com/Mottie/tablesorter/wiki).

### Features

* Multi-column alphanumeric sorting and filtering.
* Multi-tbody sorting - see the [options](//mottie.github.io/tablesorter/docs/index.html#options) table on the main document page.
* Supports [Bootstrap v2 and 3](//mottie.github.io/tablesorter/docs/example-widget-bootstrap-theme.html)

  * `package.json` files now points to the entire "dist" folder. See [issue #881](https://github.com/Mottie/tablesorter/issues/881).
  * Add `grunt quick` build to only update widget & parser files; it skips updating the dates in the widgets & combined files.

  * The `isDigit` function now reports `false` on empty strings. See [issue #865](https://github.com/Mottie/tablesorter/issues/865).
  * Add pointer events options (`pointerClick`, `pointerDown` and `pointerUp`). Fixes [issue #885](https://github.com/Mottie/tablesorter/issues/885).
  * Prevent js error when using the `computeColumnIndex` function on empty tables (used by the math widget). Fixes [issue #889](https://github.com/Mottie/tablesorter/issues/889).
  * Prevent js error when `sortList` includes an out-of-bounds column. Fixes [issue #908](https://github.com/Mottie/tablesorter/issues/908).
  * Centralize extractor & parser code; this code is used by the main build cache loop and the "addRows" & "updateCell" methods.
  * Child row content is now properly stored in row data as an array of arrays.
  * Add "o" to `sortLocaleCompare` replacement table & update docs.
  * Replace all instances of using jQuery each with plain javascript. Fixes [issue #827](https://github.com/Mottie/tablesorter/issues/827).

* Filter
  * Regex filter searches now cache the created regex object for each query to optimize speed & a regex search now properly uses case-sensitive content

  * Any match searches which target specific columns will no longer save each filter to its respective column; see ["AnyMatch Searches"](http://mottie.github.io/tablesorter/docs/example-widget-filter-any-match.html#anymatch_searches) documentation.
  * Operator filter searchs now ignore empty strings (because `"" < 10` is `true`).
  * Clean up `parseFilter` function.
  * Add `filter_childByColumn` option.
    * Setting this to `true` allows searching through the child rows by column.
    * When `false`, the search behaves as before and all child row content is included in the search of every column.

  * Hide fixed column scrollbar in IE9 & older. See [issue #135](https://github.com/Mottie/tablesorter/issues/135).
  * Update `pointer-events` and tabbing accessibility. See [issue #135](https://github.com/Mottie/tablesorter/issues/135).
  * `setFixedColumnSize` now properly updates with no set size.

    * When `true`, a fixed column overlay is added for additional styling. See [issue #887](https://github.com/Mottie/tablesorter/issues/887).
    * It includes css [`pointer-events`](http://caniuse.com/#search=pointer-events) set to `none` to allow interaction with elements underneath; make sure your browser supports it!

  * Declare font-weight separately. Thanks [nikolas](https://github.com/nikolas) ([pull #866](https://github.com/Mottie/tablesorter/pull/868))!
  * Update Boostrap v2.x theme, and add a [Bootstrap v2.x demo](http://mottie.github.io/tablesorter/docs/example-widget-bootstrap-theme-v2.html).

#### <a name="v2.21.5">Version 2.21.5</a> (4/8/2015)

* Filter
  * Cache main loop variables - speed enhancement.
  * Allow setting `filter_selectSource` along with `filter_functions` ([demo](http://jsfiddle.net/Mottie/856bzzeL/117/)).
* Resizable
  * Integrate with columnSelector. See [issue #859](https://github.com/Mottie/tablesorter/issues/859).
  * Prevent javascript error.
  * Resizable handles now properly align when the table is within a layout with margins. Fixes [issue #864](https://github.com/Mottie/tablesorter/issues/864).
* Scroller
  * Apply on initialization. Fixes [issue #860](https://github.com/Mottie/tablesorter/issues/860).

#### <a name="v2.21.4">Version 2.21.4</a> (3/28/2015)

* Core
  * Add a utility [`$.tablesorter.getColumnText()` function](http://mottie.github.io/tablesorter/docs/#function-getcolumntext).
    * This function will provide a centralized method of obtaining column data (raw & parsed text from cells) and allow processing cells.
    * I plan to update all widgets that need to interact or obtain column data to use this function in v2.22.0.
* Build
  * The build process now includes selected parsers (added `parsers` option to build json).
  * A new `jquery.tablesorter.combined.js` file is created which will contain the core plugin along with all selected widgets & parsers; a default build does not have any selected parsers.
  * This will work around, but not resolve, [issue #855](https://github.com/Mottie/tablesorter/issues/855).
* Extras
  * Update `semver.js` & `semver-mod.js` to v4.3.3.
