title: In Rich:ExtendedTable tag, how can I set the drag-and-drop property for the columns as false?
body: <p><img src="https://i.stack.imgur.com/eAJJ5.jpg" alt=""></p>
  
  <p>I have a very specific requirement: the headers in the rich-extended data-table <strong>should not be draggable</strong>. I searched for the RichFaces classes and found about the <code>rf-edt-rsz</code> class, which can be used to disable the column resizing property, which I did. </p>
  
  <p>But the last thing of the task, <em>disabling drag-n-drop property for the columns</em> is what I'm looking for. If anyone can provide me some assistance on this task, I would be grateful.</p>
