.... unfortunately when we calculate row heights automatically we try to find 
the minimum row height that will suffice. The alternative which you suggest 
would be a bit silly as each row would automatically fill up all remaining space 
in the frame and we'd need to split every table etc etc. I agree that in the 
specific case when the overall table size is fixed then it may be sensible to 
grow rows to fill up the required space. We haven't catered for that case.
