Pages are added automatically when they are needed.
One exception: table rows must fit a single page as table rows will not break across pages. Tables will break across pages, but the rows must be short enough to fit a single page.

We don't have a simple solution for that yet. You can add images to the table cell. If the table fits a single page, then you can add images after the table and place them to overlap the table.
See this thread for a different method:
