• Miscellaneous updates to the documents.

Version 2.0.23.2 (2011-10-28)

• Fixed pager size & total pages not being retained after destroying, then restoring the pager. Thanks to crush123 for reporting the problem!

Version 2.0.23.1 (2011-10-26)

• Fixed the pager plugin to prevent errors when initialized on an empty table. Fix for issue #5.
• Added a Resizable Column widget
  • At this time, this widget allows resizing the column widths from the header.
  • The column widths are not saved, but if I did consider saving the widths to local storage. I just didn't get around to doing it.
  • Demo page added.
• Reorganized the next demo links, located at the bottom of every demo page, to match the order on the main document page.

Version 2.0.23 (2011-10-18)

• Changed the dateFormat option:
• The settings are now "mmddyyyy", "ddmmyyyy", and "yyyymmdd".
• Changed the date separator to include any of the following: slash, dash, period, comma, space(s) or tab.
• The date format parser will only work with a four digit year.
• Added a demo page.

Version 2.0.22.1 (2011-10-15)

• Updated the stickyHeaders widget

  • Sticky headers will now resize with the browser window

  • Updated blue and green themes to work better with sticky headers.

  • If using the uitheme widget, make sure the 'uitheme' widget is applied before (left of) the 'stickyHeaders' widget, as follows:

    widgets: ['zebra', 'uitheme', 'stickyHeaders']
    

Version 2.0.22 (2011-10-13)

• Updated the pager plugin:

  • Fixed a problem that occurred when removeRows is set to false - fix for issue #4.

  • Added "disable.pager" and "enable.pager" methods to the pager. These are useful if you want to delete a table row with the pager applied.

    // Delete a row
    // this function targets a button with a "remove" class name inside a table row
    // *************
    // Use delegate or live because `removeRows` is set to `true` in the demo - hidden rows don't exist
    $('table').delegate('button.remove', 'click' ,function(){
      var t = $('table');
      // disabling the pager will restore all table rows
      t.trigger('disable.pager');
      // remove the chosen row
      $(this).closest('tr').remove();
      // restore pager
      t.trigger('enable.pager');
    });
    

  • Fixed the positionFixed option (which positions the pager below the table) to now include the offset option value.

  • Fixed the pager arrow buttons so that destroying and enabling the pager multiple times doesn't multiply the number of pages changed.

  • Updated the pager demo page to allow deleting rows.

  • General cleanup and added lots of comments in the plugin and demo page on what each pager option does.

• Made one minor change to the tablesorter plugin to accomidate the pager plugin using the removeRows option.

Version 2.0.21.1 (2011-10-11)

• Added "stickyHeader" widget to the "jquery.tablesorter.widgets.js" file.
  • This widget makes the header stick to the top of the page while scrolling down.
  • The sticky header is fully functional and will allow you to sort the table.
  • And best of all, it can be applied to the original tablesorter plugin.
  • Thanks to Chris Coyier and his post on persistent headers.
• Added a compressed widget file named "jquery.tablesorter.widgets.min.js".

Version 2.0.21 (2011-09-22)

• Added sortBegin event
  • This event is triggered immediately before the actual sort. So this event occurs after the sortStart and after the sortList option has been updated.
  • It was added to allow for changing the sort dynamically. See issue #3.
• Added removeRows option to the pager plugin
  • When true, the default value, the pager plugin removes all non-active rows from the table. This greatly increases the sort speed of large tables.
  • When false, the pager plugin merely hides the non-active rows so they all continue to exist in the table. This should allow for better access to data within the table (i.e. submitting form elements)

Version 2.0.20.1 (2011-09-16)

• Oops fixed currency sorting

Version 2.0.20 (2011-09-16)

• Filter Widget
  • Added "filter" to the "headers" option to allow disabling the filter option for a specific column - thanks jizo!
  • Added "filter-false" class, that when applied will disable the filter widget for that column.
  • Updated the headers docs and the filter widget demo.
• Updated the currency parser to use unicode characters to better work in different document formats.

Version 2.0.19 (2011-09-16)

• Added code in attempt to clear the table headers between multiple tables - fix for issue #2.
• Cleaned up some code and wrapped the widget code to prevent conflicts with other javascript libraries.
• Updated the columns widget:
  • Added css examples to the demo.
  • Removed the widgetColumns option from the core, but it is still used by the widget - the way it is used hasn't changed.
• Updated the uitheme widget:
  • Added widgetUitheme option - used by the widget, but not included in the core. See the demo for a better example.
  • Example added to the uitheme widget demo.

Version 2.0.18.1 (2011-09-14)

• Updated the "uitheme" widget with method to add zebra striping and hovered header classes.

Version 2.0.18 (2011-09-13)

• Fixed a bug in the column widget, it would cause an error if no initial sort was set.
• Fixed a bug where an error would occur if a widget doesn't exist.
• Updated pager widget to allow restoring the pager plugin & updated demo.
• Added column filter widget. It is designed so that each column has an filter.

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) 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 demo and Updating a table cell.

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 cells.
  • 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 demo.
  • Thanks to Eugene Ivakhiv for bringing this issue to my attention in my blog.
