[Zope] OT: Zope/ReportLab/PDF generate left aligned tables

19 Oct 2000

      Hi,
Is anybody out there using ReportLab PDF library ?

I successfully installed ReportLab and PIL to serve out pdf files with
Zope.
Now I'm in trouble with reportlab.platypus.SimpleDocTemplate ,Table.
I can't figure out how to draw a table left aligned on a PageTemplate.
I can set several styles of table cells but wehrer can I set the
alignment of a table within it's frame?
