This question already has an answer here:
I have the following problem:
My section 7.2 contains a lot of tables. Now it shows 2 tables, and then there is a space left on the page, that is not big enough for the next table. Therefore, section 7.3 starts at that empty space. However, after that, there are still two pages full of tables that belong to section 7.2, so I prefer section 7.3 to start after these tables.
Is this possible?
