[reportlab-users] Re: Getting the number of lines in a frame

[John Pywtorak]

The problem with your second issue (ValueError exception below) I 
believe is the for loops creating the headings and texts arrays and then 
the line:
data = (headings, texts), (headings, texts)
Take a look at data it is created wrong for Table.  I think you are 
getting something like
data = (((Paragraph, ...), (Paragraph, ...)), ((Paragraph, ...), 
(Paragraph, ...)))
It needs to be
data = (
#Row 0
('Col 0', 'Col 1', '...'),
#Row 1
('Col 0', 'Col 1', '...'),
#Row ...
)

Hope this helps.
