Forum How do I...?

Fitting tables without paragraph run-on

I have fixed 6 tables sequentially... If a page has 25% of space in the bottom, where the first 5 tables are positioned, then paragraph below the 6 tables should not run into that space. But if there is page space below the sixth table, then it should run-on.
How do it do this?
I'm afraid I don't quite understand the question! Could you provide an example?
