[reportlab-users] Struggling with SimpleDocTemplate

[Charlie Clark]

Further to my mail this morning I'm including the source.

I think I have solved the problem with the image: it actually seems to be 
down to setting the row height in which case Platypus seems to enforce 
vAlign = bottom for the cells.

The task is to create ten 50mm x 90mm badges per page in two columns with a 
4mm border between columens and 3mm between rows. The page is A4 and the 
margins are 13mm and 15mm respectively.

I've had to use tables in tables to solve some issues: Images and Text in 
the same table cell and it seems at the moment that the best thing to do is 
to use Spacers in table cells rather than relying on rowHeights. I'd 
appreciate alternative solutions.

With BoundaryOn and Grid enabled it is possible to see that the main table 
is indented about 2 mm from the left and top of the enclosing frame. How do 
I get rid of this having already set padding for the document to be 0?

Help appreciated
