[reportlab-users] Table cell too large vertically

The amount of data varies widely and is user input.  I can't predict the
length.  So, reducing the font won't work.

I tried to ball park the max size and split the data myself onto several
table rows.  That works but is as ugly as can be.  I never know where on
the page the system will be when encountering a row that is too big, so I
don't know how much space I have left.

Having written several report generators over the years, I think the
algorithm should be:

if row is too big for an entire page
    while more text
        print as much as you can on the current page
        reduce text by what was printed
        page break
else if row is too big for the current page (but small enough for a new
    page break
    print row
    print row

Other than this fix on the reportlab end, I don't think there is a way for
me to create a decently laid out report in this case.
