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.

### Change Log

View the [complete listing here](https://github.com/Mottie/tablesorter/wiki/Change).

#### Version 2.7.11 (2/24/2013)

* Fixed several javascript errors:
  * Empty cells in a numeric column should no longer cause an error - fixes [issue #246](https://github.com/Mottie/tablesorter/issues/246).
  * The tablesorter storage function should no longer cause an error when provided an undefined key - fixes [issue #244](https://github.com/Mottie/tablesorter/issues/244).
* Added `saveSortReset` method to clear any saved sorts for a specific table. Use it as follows:

    ```javascript
    $('table').trigger('saveSortReset');
    ```

* Added `delayed` options to several filter formatter functions.
  * Selectors that can be changed quickly - uiSlider, uiRange, uiSpinner, html5Range and html5Number - will now execute the filter query after a short delay.
  * The filter delay time is set in the filter function option `filter_searchDelay`. The default delay is 300 milliseconds.

#### Version 2.7.10 (2/22/2013)

* Updated widget storage function to ensure no invalid strings are passed to the `$.parseJSON` function.
  * Thanks to [andriijas](https://github.com/andriijas) for the code suggestion :)
  * Fixes [issue #240](https://github.com/Mottie/tablesorter/issues/240) & [issue #244](https://github.com/Mottie/tablesorter/issues/244).
* Updated filter widget:
  * When cell content contains quotes and the filter select is added, the quotes are now properly processed to be included within the options. Fixes [issue #242](https://github.com/Mottie/tablesorter/issues/242).
  * Empty cells are no longer added to the options. If you want to include empty cells, add the following (see [this StackOverflow question](http://stackoverflow.com/q/14990971/145346)):

    ```html
    <span style="display:none">{empty}</span>
    ```

    Then you'll get a select dropdown showing `{empty}` allowing you to select empty content.

#### Version 2.7.9 (2/20/2013)

* Fixed an issue with the pager targetting an incorrect page when the table starts out empty.
* Get the correct number of columns when `widthFixed` is `true` and the first row contains a table. See [issue #238](https://github.com/Mottie/tablesorter/issues/238).

#### Version 2.7.8 (2/17/2013)

* Fixed script errors:
  * Comment start was stripped when converting files from UTF-8 w/BOM to UTF-8 w/o BOM.
  * Fixed Firefox error in the filter-formatter files, when HTML5 elements don't exist, oops!

#### Version 2.7.7 (2/17/2013)

* Updated the currency parser to ignore formatting (commas, decimals and spaces) when detecting the column parser.
* Updated the natural sort regex to better work with scientific notation and alphanumerics with the number first - see [this issue](https://github.com/overset/javascript-natural-sort/issues/8).
* Reverted code to only add a colgroup if the [`widthFixed`](http://mottie.github.com/tablesorter/docs/#widthfixed) option is `true` and no colgroup exists. Fixes issues [#238](https://github.com/Mottie/tablesorter/issues/238) and [#239](https://github.com/Mottie/tablesorter/issues/239).
* Added a tablesorter namespace to all bound events. Fixes [issue #233](https://github.com/Mottie/tablesorter/issues/233).
* Added a [`filterReset`](http://mottie.github.com/tablesorter/docs/#filterreset) method which is the same code executed when the [`filter_reset`](http://mottie.github.com/tablesorter/docs/#widget-filter-reset) element is clicked.
* Added a `pageSet` method to the pager which allows you to easily change the pager page (see [issue #231](https://github.com/Mottie/tablesorter/issues/231)):

    ```javascript
    // go to page 3
    $('table').trigger('pageSet', 3);
    ```

* Added a range filter to the filter widget.
  * You can now search for a range of values using either of these formats: `10 - 20` or `10 to 20`. Note the space before and after the dash so as to differentiate it from a negative sign.
  * You can also use symbols within the range `10% - 20%` or `$10 - $20`.
  * Thanks to [matzhu](https://github.com/matzhu) and [satacoy](https://github.com/satacoy) for code ideas in [issue #166](https://github.com/Mottie/tablesorter/issues/166#issuecomment-10167129).
* Added logical AND and OR operators to the filters to the filter widget.
  * Entering `box && bat` (or `box AND bat`) will only show rows that contain `box` and `bat` within the same column below the filter. It does not search other columns. The spaces between the operators and the queries are important.
  * Entering `box|bat` (or `box OR bat`) will only show rows that contain either `box` or `bat` within the same column below the filter. It does not search other columns. The spaces between the operators and the queries are important.
  * At this time you cannot combine different operators. So, `>= 100 AND <= 200` will not work, use the range filter operator (`100 - 200`) instead.
  * Using the `|` (or operator) was previously undocumented, but useable.
  * This was also requested in [issue #166](https://github.com/Mottie/tablesorter/issues/166).
* Added a new filter widget option named [`filter_formatter`](http://mottie.github.com/tablesorter/docs/#widget-filter-formatter):
  * This option allows you to add custom selectors into the filter row.
  * Because of the amount of coding, new files named "jquery.tablesorter.widgets-filter-formatter.js" and "filter.formatter.css" were added. They include code to add jQuery UI and HTML5 controls via the filter_formatter option.
  * Filter formatter functions include: "uiSpinner", "uiSlider", "uiRange" (uiSlider ranged), "uiDatepicker" (range only), "html5Number", "html5Range" and "html5Color".
  * As an example, this code will add the jQuery UI spinner to the first column:

      ```javascript
      filter_formatter : {
        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, // enable or disable the control
            exactMatch: true,
            numberFormat: "n"
          });
        }
      }
      ```

  * You can also choose to add the current selector value into a css3 tooltip or into the header by setting the `valueToHeader` option, if available.
  * Fulfills [ErinsMatthew](https://github.com/ErinsMatthew)'s feature request - [issue #232](https://github.com/Mottie/tablesorter/issues/232). Thanks for the great idea!
* NOTE: I know the js folder is getting messy. In version 3, I plan on having a separate folder for widgets and parsers. And with the build system, you'll be able to pick and choose which components you need.


#### Version 2.7.6 (2/6/2013)

* Merged in an update from [Somebi](https://github.com/Somebi) to fix a javascript error which occurs when the table doesn't have a thead or tbody, or it is already initialized.
