you won't get access to the next flowbale from inside a flowable.
You must either mess with the frame or create a flowable that contains your flowables.
That is the preferred route as it localizes the changes. Logically you need a table
and a summary flowable. If you know the width you can work out how to expand the
whole table + Summary so the summary ends up at the bottom of a frame. There will be
some special cases.
