* Parsers for sorting text, alphanumeric text, URIs, integers, currency, floats, IP addresses, dates (ISO, long and short formats), time. [Add your own easily](http://mottie.github.com/tablesorter/docs/example-parsers.html)
Included all original [document pages](http://mottie.github.com/tablesorter/docs/index.html) with updates from my blog post on [undocumented options](http://wowmotty.blogspot.com/2011/06/jquery-tablesorter-missing-docs.html).
* 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.
* 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).
* 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
* 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.
* 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.
