[reportlab-users] Splitting tables across pages and choosing templates accordingly

Following up on this, I'm seeing PageTemplate.afterDrawPage's
docstring reads:

    This is called after the last flowable for the page has been
    processed. You might use this if the page header or footer needed
    knowledge of what flowables were drawn on this page.

Isn't this precisely what I need? I want to know if a full table has
been written on this page or not. How do I get this information? I
would expect that the doc argument passed to the PageTemplate should
know which flowables it has and which ones it has processed. How do I
find out?

Thanks,
