Table won't break to next page in the right position

Hi!

I've been trying to fit a long table into a book's pages without leaving a big blank space and I can't.

I'm sending two images, one of how the table ocuppies the space beyond the page, and one of what happens when I fit the text frame on the page's boarders (the table breaks on the top, leaving a big blank space).

Hope somebody can help. Thank you!
