docbook table in oxygen

Hi I have a little problem with a docbook table...actually I have serval.

1. I scan a xml document for my information and each time I find the information the xquery creates a new table. How can I get only one table?? and only write the header on the top of new pages? (If you need code just write me)

2. I want to rotate a table and set it landscape. Can anyone help me?
