title: Vertical Table Header Cell Renderer
body: <p>I used the Vertical Table Header Cell Renderer that is available in this site <a href="http://tips4java.wordpress.com/2009/03/06/vertical-table-header-cell-renderer/" rel="nofollow">here</a>
  It works great for me but I need a clue on how can I have in some headers that are vertically aligned multiple rows like this you can see in the image of the example (Coordinate Geometry). I tried to set the strings with the appropriate \n character but I think my approach is very simplistic and wrong.
  Please keep it simple. 
  Thank you!</p>
