I have implemented the 3rd party drag and drop plugin
(jquery.tablednd_0_5.js from
http://www.isocra.com/2008/02/table-drag-and-drop-jquery-plugin/)
to the Flexigrid. I have not added the drag/drop events through to
markup so that you can edit it easily, but the code is in place and
can be modified within the flexigrid.js file. If anyone is interested
in the code, please let me know.
