Numbers will flow a table across page breaks, so you don't have to identify the break, as I think you know. There is no reason to be moving content from one table to another table. If you want to break a table sooner than necessary, for some formatting reason, Insert a blank row and size the row to force lower rows to the next page. In Print View, you can see what is going to happen when you print. If layout is your top concern, do your editing in Print View.
