Overset text in cells, but can't resize table row

I'm working on a document with a very long table that flows through text boxes from one page to the next. I can clearly see that there's space at the bottom of the page, but I can't seem to increase the size of the cells or row any more. When I try to drag down with the arrow, nothing happens. When I try to adjust manually, I'm met with a window that says "The value must be between 0.0417 in and 8.3333 in." Can anyone help me increase the length of the cells so that there's not overset text, and the space at the bottom of the page is filled? Thanks!
