Rails - Feb 2006 - wish list for table column sorting

Is there a plugin that does this?

   * Provides ordering for columns in tables, asc and desc

   * Integrated with paginator

   * Reorders through AJAX calls

   * Gives access by API to the column being used
     and whether the order is asc or desc to be able
     to mark it in the header somewhow

   * Supports cells coming from different models
