[reportlab-users] Problems with filling cells with large paragraphs (LayoutError: Flowable)

[Nathan]

I'll second this request for help.  I've run into the same two issues.
 I've been trying to work around the "Paragraph too large" error by
catching the crash and then splitting all large-looking paragraphs
into smaller paragraphs and using more rows in the table and then
redoing the template and rebuilding, but that's a rather messy method
and almost doubles my code length, not to mention that I end up with
more rows than I should.

Seems like table cells just need to be able to split across multiple pages.
