[reportlab-users] Composing Tables Without Platypus?

I've re-read the Users Guide, API, textobject.py, and canvas.py without
seeing how to print tabular data with the fine positioning control offered
by the canvas. My learning script is attached, and I'd greatly appreciate a
nudge in the proper direction.

Also suggestions and recommendations based on your experiences are most
welcome. Eventually -- and Real Soon Now, I hope -- I want to retrieve the
data in table 't' from a database table and print three pages, one for each
set of data, with the pdf file name filed in appropriately for each page.
