Expanding text fields in a table cause the bottom of the document to disappear, how can I make it expand onto another page?

I have a document that is mainly one large table and it includes comment boxs that expand as more text is entered. However when these boxes expand it pushes the bottom of the document into never never land.. it just disappears! I have no idea how to have it so when a comment box expands and it moves the info below that the info continues onto the next page, please advise!
