The JWebSwing implementation for Data Tables

The newest version!

/*
 * Adds a new sorting option to dataTables called `date-dd-mmm-yyyy`. Also
 * includes a type detection plug-in. Matches and sorts date strings in
 * the format: `dd/mmm/yyyy`. For example:
 * 
 * * 02-FEB-1978
 * * 17-MAY-2013
 * * 31-JAN-2014
 *
 * Please note that this plug-in is **deprecated*. The
 * [datetime](//datatables.net/blog/2014-12-18) plug-in provides enhanced
 * functionality and flexibility.
 *
 *  @name Date (dd-mmm-yyyy)
 *  @summary Sort dates in the format `dd-mmm-yyyy`
 *  @author [Jeromy French](http://www.appliedinter.net/jeromy_works/)
 *  @deprecated
 *
 *  @example
 *    $('#example').dataTable( {
 *       columnDefs: [
 *         { type: 'date-dd-mmm-yyyy', targets: 0 }
 *       ]
 *    } );
