title: BIRT: Alternating row Color in a table group
body: <p>Has anybody an idea of how the highlighting condition has to look like, to create alternating rows in groups? I want the every row with an even number of a table group (not of the whole table) to have a different color.</p>
  
  <p>Thanks in advance! :-) </p>

  <p>P.S.: I'm using BIRT 2.1.3</p>
