How do you insert a page break within a table in Microsoft WORD 2007?

I have a very large document I'm working with. There are different tables throughout. How do I control where the Page Break is inserted?

I also can't figure out how to control the exact placement of the table. I have typed a heading outside of the table. If I grab the table and move it, sometimes the table jumps above the heading in the document.

This is extremely frustrating.

Thanks for any help!
