### Change Log

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

#### Version 2.1.19 (4/23/2012)

* The filter widget will now ignore leading spaces so when the `filter_startsWith` is `true` it will match the text. Fix from [issue #55](https://github.com/Mottie/tablesorter/issues/55). Thanks to [aarkay18](https://github.com/aarkay18) for the code!
* Fixed a problem with empty table cells returning an empty string instead of parsing the cell - needed when there is HTML like an input tag to process. Reverted the change accidently added back in version 2.1.15.
* Added a resort flag that when set to false, it will prevent the resorting of the table when "update", "updateCell" or "addRows" is called. Use the appropriate format below:
  * *update*: `$('table').trigger('update', [false]);
  * *updateCell*: `$('table').trigger('updateCell', [ this, false ]);` - see the [updating a table cell](http://mottie.github.com/tablesorter/docs/example-update-cell.html) demo.
  * *addRows*: `$('table').trigger('addRows', [$row, false]);` - see the [adding table rows](http://mottie.github.com/tablesorter/docs/example-add-rows.html) demo.

#### Version 2.1.18 (4/23/2012)

* When the sticky headers widget is applied to a table with multiple header rows, adding the class name `sticky-false` to any header row will prevent it from becoming sticky. Thanks to [megatom](https://github.com/megatom) for the suggestion in [issue #52](https://github.com/Mottie/tablesorter/issues/52#issuecomment-5261303)!
* Updated filter widget css to better work with twitter's bootstrap. Fix per [issue #54](https://github.com/Mottie/tablesorter/issues/54). Thanks [thezoggy](https://github.com/thezoggy)!
* Modified the green theme arrows; see the [columns style widget](http://mottie.github.com/tablesorter/docs/example-widget-columns.html) demo and choose the green theme to see the change. I've included the PSD files as well.

#### Version 2.1.17 (4/21/2012)

* Fixed an error reported in [issue #52](https://github.com/Mottie/tablesorter/issues/52) which occurrs when using the metadata plugin after the last update.
* The sticky headers widget will now work properly if TD's are included in the header, but the following should be noted:
  * The `selectorHeaders` option needs to be changed to `thead th, thead td` to properly include the TD's.
  * CSS changes to the blue theme were needed and most likely any custom themes to add a background color to these cells.
  * To prevent the TD's from being sortable, add a `sorter-false` class name to it.
* Updated the blue theme:
  * TD's in the sticky header should now have a background color applied.
  * Replaced the black arrow background image gifs with data uri. Included comments with white arrow data uri.
* Updated filter widget to more accurately count the number of columns. There was an issue with multiple header rows.

#### Version 2.1.16 (4/20/2012)

* Removed `emptyToBottom` option. It has been replaced with the `emptyTo` option.
* Added `emptyTo` option:
  * Setting it to `top` will always sort all empty table cells to the top of the table.
  * `bottom` will always sort all empty cells to the bottom of the table.
  * `none` or `zero` will treat empty cells as if their value was zero.
  * Individual columns can be modified by adding the following, set in order of priority:
      * metadata `class="{ empty: 'top' }"`. This requires the metadata plugin.
      * headers option `headers : { 0 : { empty : 'top' } }`.
      * header class name `class="empty-top"`.
      * Overall `emptyTo` option.
  * Updated the [sorting empty cells](http://mottie.github.com/tablesorter/docs/example-option-sort-empty.html) demo.
  * Fix for [issue #48](https://github.com/Mottie/tablesorter/issues/48).

* Add `stringTo` option in version 2.1.16. This options sets the string value for all of the numerical columns.
* Modified the `string` option which is only applied to text within a numerical column; setting the value to:
  * `max` will treat any text in that column as a value greater than the max (more positive) value. Same as the `max+` value, which was retained for backwards compatibility.
  * `min` will treat any text in that column as a value greater than the min (more negative) value. Same as the `max-` value.
  * `top` will always sort the text to the top of the column.
  * `bottom` will always sort the text to the bottom of the column.
  * `none` or `zero` will treat the text as if it has a value of zero.
  * Individual columns can be modified by adding the following, set in order of priority:
      * metadata `class="{ string: 'top' }"`. This requires the metadata plugin.
      * headers option `headers : { 0 : { string : 'top' } }`.
      * header class name `class="string-top"`.
      * Overall `stringTo` option.
  * Updated the [text strings in numerical sort](http://mottie.github.com/tablesorter/docs/example-options-headers-digits-strings.html).
  * Fix for [issue #50](https://github.com/Mottie/tablesorter/issues/50).

* Fixed sticky header widget to now include multiple rows. Fix for [issue #52](https://github.com/Mottie/tablesorter/issues/52).

#### Version 2.1.15 (4/18/2012)

* Modified the `emptyToBottom` option:
  * Clarified that setting this option to `null` will treat empty cells as if they had a value of zero. Fix for [issue #48](https://github.com/Mottie/tablesorter/issues/48).
  * Modified the script so that empty cells do not call their respective parser to keep the `emptyAtBottom` functionality working properly. Fix for [issue #49](https://github.com/Mottie/tablesorter/issues/49).

#### Version 2.1.14 (4/17/2012)

* Updated "shortDate" parser to include the time, if provided. I've also updated the [Changing the date format](http://mottie.github.com/tablesorter/docs/example-option-date-format.html) demo with a few times.

#### Version 2.1.13 (4/17/2012)

* Modified "digit" parser to not remove alphabetical characters as it was breaking the [text strings in numerical sort](http://mottie.github.com/tablesorter/docs/example-options-headers-digits-strings.html) functionality.
