[reportlab-users] Reducing the margin of a table

[Claudio Battaglino]

In your example, if you don't specify rowHeights you have a bottom margin.
The User Guide says:
"The rowHeights argument is a sequence of numbers or possibly None, 
representing the heights of the rows....A value of None means that the 
corresponding row height should be calculated automatically".

The following table, for example, doesn't fill the page.
So I must specify rowHeights.
I thought this was done automatically.


t = Table([['This is a single cell table']],
                 colWidths=PAGE_WIDTH,
                  style=TableStyle([
                         ('LEFTPADDING',(0,0),(-1,-1), 0),
                         ('RIGHTPADDING',(0,0),(-1,-1), 0),
                         ('BOX',(0,0),(-1,-1), 0.1, colors.blue),
                         ],
                     ),
                  )


However I solved the problem specifying rowHeights.
I don't like it but it works.

Thank you very much for your help.
