1. How do create a table that spans over numerous pages without splitting the table rows?

Please describe in more detail what you mean by "without splitting
table rows". Your table seems to contain only a single row, if there
is enough content in one of the cells that it overflows a page, the
row content has to be broken across the pages.
If you are actually looking for content being kept toghether, see
 http://xml.apache.org/fop/faq.html
question 3.6, and the appropriate spec section.

2. How do I create a table header that spans across numerous pages and appears at the top of the table on each page?
