title: GWT draggable CellTable cells
body: <p>I have a GWT CellTable - it's a pretty simple table with just a single string column.</p>
  
  <p>What I'd like to do is drag rows of this table to a drop target (actually another table).  I've been trying to figure out how to attach a draggable event as described at ~23:00 of <a href="http://www.youtube.com/watch?v=KEkR1ox_K10" rel="noreferrer">this video</a>.  </p>
  
  <p>To which CellTable element can I set the draggable flag to TRUE.</p>
  
  <p>I haven't gotten this far yet, but I'm sure I'll soon face a similar issue in setting the drop handler on the target table.</p>
  
  <p>If someone could post an example or point me in the right direction, I'd be grateful.</p>
