TableSorter Change Log

Version 2.0.17 (2011-09-11)
============================

* Added a jquery.tablesorter.widget.js file:
  * It contains the "uitheme" widget, to add any jQuery UI theme, and the new "columns" widget, to style columns.
  * The blue and green themes have been updated with the added styles from the columns widget.
  * Added a Columns Widget demo and instructions.
* Added a `widgetColumns` option which defines the css classes added by the columns widget.
* Added notes to the pager plugin demo page to better specify when a change was added.
* The green theme header images have been modified to better work with variable width tables.

Version 2.0.16 (2011-09-08)
============================

* Added notes to demo pages to indicate if the original (version 2.0.5, at [tablesorter.com](http://tablesorter.com/docs/)) does have that option or method.
* Added "addRows" method that allows adding table rows.
  * This method differs from the "update" method in that it only adds rows to the cache.
  * Use this new method to add rows to a table with the pager plugin applied. Using the "update" method on a table with the pager plugin will remove all hidden rows from the cache.
* Added a "destroy.pager" method to remove the pager from the table - pager demo updated.

Version 2.0.15 (2011-08-23)
============================

* Fixed a problem that caused a javascript error when a table header cell doesn't have a class name.

Version 2.0.14 (2011-08-22)
============================

* Reverted the changes made in 2.0.13 and added checks to prevent errors.
* Allowed sorting an empty table which would then automatically sort its contents when the table is updated.
* Modified "Update" and "UpdateCell" methods to automatically resort the table using the existing sort.
* Updated the [Initializing tablesorter on an empty table](http://mottie.github.com/tablesorter/docs/example-empty-table.html) demo and [Updating a table cell](http://mottie.github.com/tablesorter/docs/example-update-cell.html).

Version 2.0.13 (2011-08-19)
============================

* Fixed a problem where a javascript error would occur when initializing a multi sort on an empty table. Thanks again to Eugene Ivakhiv!

Version 2.0.12 (2011-08-19)
============================

* Updated the `textExtraction` functionality
   * The original textExtraction function was only able to be applied to all the cells in the table.
   * Apparently the ability to define textExtraction on a per column basis was misinterpreted by me, so now I've added it.
   * Use the option as follows:

     $("table").tablesorter({
       textExtraction: {
         0: function(node) { return $(node).find(selector1).text(); },
         1: function(node) { return $(node).find(selector2).text(); },
         // etc
       }
     });

   * Updated the [Dealing with markup inside cells](http://mottie.github.com/tablesorter/docs/example-option-text-extraction.html) demo.
   * Thanks to Eugene Ivakhiv for reporting this issue to my attention in my blog.


Version 2.0.11 (2011-08-04)
============================

* Added the ability to set a column parser using a class name
   * When setting the parser, start the class name with "sorter-" followed by the parser name, e.g. "sorter-text" or "sorter-digit"
   * The column can be disabled by setting the class name to "sorter-false"
   * [Demo page](http://mottie.github.com/tablesorter/docs/example-parsers-class-name.html) included.
   * Custom parsers can also be used - see the updated [writing custom parsers demo](http://mottie.github.com/tablesorter/docs/example-parsers.html).

Version 2.0.10 (2011-07-31)
============================

* Modified the numeric sort with a new method to deal with non-numeric content:
   * When sorting columns with numeric values, by default any non-numeric or empty cells are treated as if they have a zero value. This puts the text between negative and positive values in a column.
   * Adding `string : "max+"` to the `headers` option will now treat any non-numeric table cells as if they have a maxiumum positive value (a value greater than the maximum positive value in the column).
   * Adding `string : "max-"` to the `headers` option will now treat any non-numeric table cells as if they have a maxiumum negative value (a value greater than the maximum negative value in the column).
   * See the "[Dealing with text strings in numeric sorts](http://mottie.github.com/tablesorter/docs/example-options-headers-digits-strings.html)" demo for a better visual example.
* Changed UI theme widget code to use "ui-widget-header" instead of "ui-widget-default" to better match the themes.
* Renamed changelog.markdown to changelog.txt to prevent downloading when clicking on the link

Version 2.0.9 (2011-07-27)
============================

* Added a jQuery UI theme and widget example. To apply the jQuery UI theme:
   * Include any jQuery UI theme on your page.
   * Add the base tablesorter ui theme (located in css/ui directory)
   * Add the jQuery UI theme widget code found on [this example page](http://mottie.github.com/tablesorter/docs/example-ui-theme.html). This demo page includes the UI theme switcher.
* Added a header index to the `onRenderHeader` function to make it easier to target specific header cells for modification. See the [render header example](http://mottie.github.com/tablesorter/docs/example-option-render-header.html) for an example.
* Pager plugin updates:
   * Removed the `separator` option and added an `output` option which allows you to completely customize the output string.
   * In the `output` string, include any of the following variables:
      * `{page}` is replaced with the current page number.
      * `{totalPages}` is replaced with the total number of pages.
      * `{startRow}` is replaced with the number of the visible start row of the pager.
      * `{endRow}` is replaced with the number of the visible end row of the pager.
      * `{totalRows}` is replaced with the total number of rows.
   * The `cssPageDisplay` option can now target any element; in previous versions, this element was an input of type text.
   * Added a `pagerArrows` and `cssDisabled` options:
      * When `pagerArrows` is true, the first and previous pager arrows have the css class name contained in the `cssDisabled` option applied when the first row is visible.
      * The next and last pager arrows will be have the `cssDisabled` class applied when the last row is visible.
      * Additionally, if the number of table rows is less than the pager size, the pager will get the `cssDisabled` class name applied.
      * If false (the default setting), the pager arrows class names will not change.
      * Please see the updated [pager demo](http://mottie.github.com/tablesorter/docs/example-pager.html) to see this working.

Version 2.0.8 (2011-07-21)
============================

* Fixed parsers for currency and digits to work with number values separated by commas. Thanks to Josh Renaud for the information!
* Fixed "lockedOrder" header option and added documentation and an example on how to use it.
* Made the sort order "desc" only trigger off of the first letter, so any word/abbreviation starting with "d" will set the descending sort order, all other letters will set the order to ascending (shhh, because I'm a bad speller :P)
* Modified the "sortInitialOrder" option so it can also be set in the headers option.

Version 2.0.7 (2011-07-17)
============================

* Added "pagerChange" and "pagerComplete" events to the pager plugin which trigger on the table. See the [pager demo](http://mottie.github.com/tablesorter/docs/example-pager.html) for an example on how to bind to them.
* Added the "sortAppend" since the option was there, but apparently the code wasn't.
* Added missing documentation from [my blog post](http://wowmotty.blogspot.com/2011/06/jquery-tablesorter-missing-docs.html)
 * This included a few new example pages: apply widgets, child rows, render header, sort append and zebra widget.
 * Added a methods and events table.
* Fixed the minified version. Apparently sorting functions called by the eval were removed by the Google Closure Compiler. Resolved by using "Whitespace only" optimization.
* Fixed syntax highlighting; updated Chili.

Version 2.0.6 (2011-06-22)
============================

* Forked original files and docs from [tablesorter.com](http://tablesorter.com) to GitHub.
* Replaced alphabetical sort with an alphanumeric sort
 * This "slower" sort can be disabled by setting the `sortLocaleCompare` option to `true`
 * The `sortLocaleCompare` option's default was changed to `false`.
 * Added a very basic demo.
* Added `tableClass` option
 * The value is "tablesorter" by default and should no longer be required in the default markup.
 * This class is applied to the table in the script and should match the css styling.
* Each header cell now has its content wrapped with a span.
 * This allows applying the direction icon to the span instead of the entire cell.
 * Although, this might just be extra markup with the advent of multiple background images and gradient backgrounds available in CSS3.
* Reformatted the code to make jSLint "happier".

Version 2.0.5b (?)
============================

* General
 * Added "cssChildRow" option - attach a child row to its parent.
 * Added "sortLocaleCompare" to use the native `String.localeCampare` method during text sort.
 * Added "onRenderHeader" function that is called when classes are added to the header cells.
 * Added "selectorHeaders" option to target the the header cells.
 * Changed multisort function

Version 2.0.3 (2008-03-17)
============================

Version 2.0.2 (2008-03-14)
============================

 * Added support for jQuery 1.2.3.
 * Added support for decimal numbers and negative and positive digits.

Version 2.0.1 (2007-09-17)
============================

 * Added support for jQuery 1.2.
 * Added new Minified version of tablesorter.
 * Updated documenation and website with new examples.

* Bug fixes
 * If row values are identical the original order is kept (Thanks to David hull).

 * zebra widget. (Thanks to James Dempster).
