title: GWT - TreeTable?
body: <p>I'm looking for a way to extend GWT FlexTable or CellTable to a "TreeTable". I want a table with expandable rows, and I want to be able to get the data from the sever when it's needed. So I don't want to populate the whole table (all levels) from the start.</p>
  
  <p>Is it best to use a FlexTable or a CellTable to start with? Or are there any examples/plugins on the web for this?</p>
  
  <p>All ideas and tips are appreciated!</p>
