title: jface tableviewer cell-span
body: <p>I am endeavouring to render some hierarchic data in a <code>TableViewer</code> (the <code>TreeViewer</code> isn't a good fit - trust me on this :-). Consequently I need to render the parent cells with a row-span > 1.</p>
  
  <p>As far as I can tell, this currently isn't possible with the regular JFace <code>TableViewer</code>, or the SWT <code>Table</code> underneath.</p>
  
  <p>Can anyone tell me I'm wrong?</p>
  
  <p>M.</p>
