I have an appendix section with half a page of text followed by a lot of tables. I want all these tables to go on float pages for the nice distribution on the pages, so placement specified as [p]. First there are five tables of same size belonging together, two of them fitting on a page. Next there are two tables belonging together and fitting on a page together. Then again two tables belonging together and fitting on a page together. Problem is if I just let Latex do what it does, it puts the first two tables on a page, then the next two on a second page, but then the last one of the first five and the first of the first group of two on a page, so exactly not putting the tables together that belong together.
What I want is to tell Latex to let the fifth table be alone on a its float page and continuing with the rest on the next page.
I tried \clearpage, \pagebreak, \newpage and even \FloatBarrier. \clearpage and \FloatBarrier do what I want but with the ugly side effect of inserting a whole blank page. This blank page is probably a normal page followed by the float pages. Problem is I have no text or other stuff to fill that blank page so it stays blank and is completely unnecessary.
Is there a way to solve this? How can I suppress the creation of the non-float-page blank page? How can I control the placement of the floats on the float pages in such a case where text between the floats is completely absent? Can I group floats to specify which should be put together? Can I mimic the float placement of float pages on normal pages? Can I define invisible floats that act as space in float pages to control which floats are placed on a page together?
