[Zope] Create Reports as PDF

Hi all! I've just read the "Create a PDF on the fly" How-To, so creating a document (ZPT or DTML) which gets downloaded as PDF shouldn't be a real problem. But there's one question left: I'd like to create a report which exists primarily of tables (about 4 or 5 per document) plus header and footer. Can I avoid that the page break appears in the middle of a table, and how? You know, like the most report generators do if you tell them "don't split this group" or something similar... Thanks! Martin
