[reportlab-users] Table cell too large vertically

[Blake McBride]

Yes, with multiple columns it is a little more complex.  But, this is a
serious problem, and must be handled at the reportlab level if it is to be
handled correctly.  I'd think for someone familiar with the code this could
be a two or four hour project.  Well worth the effort to solve a
fundamental issue.  Just my 2 cents...

As it is, I guesstimated the max length and split large rows into multiple
rows.  It is an ugly solution but allows me to move forward.

Thanks.
