title: Fixed size of detail block regardless of row count
body: <p>I am trying to design an invoice where the detail block with rows of data will be fixed size. I'm using <em>iReport 5.6</em>. After the detail block, there will be subtotals and totals. A detail block can span multiple pages. Anyone got any idea? I am new to <em>iReport</em>. I tried myself and searched a lot. But no luck. Can anyone help me please?</p>
  
  <p>Here is a sample invoice.</p>
