```Ok, I get it now. I've done something similar but for width.

things easier.
Basicaly I walked the table structure and placed the cell contents in to a
Paragraph object and used the "breakLines" method to get the contents width
(in your case give it a width and let it calculate the height). I went
through each cell till I found the largest cell, for each column and made
that the columns width.

Something similar could be done to calculate the height of each row.

Their may be a better way...This is the only one I found. Hope this helps!
