How can I rotate only one page or table inside a document?

Question

I have the following situation:

• A table is too large for a portrait PDF size
• I can split them up or make the side landscape. I tried both approaches, but they are not sufficient to solve the whole bunch!

I tried to make it landscape via the hints here: How to change certain pages into landscape/portrait mode It doesn't work. I get some strange error in the table, like the [!htbp] has an error. After removing them, same error was generated now by \renewcommand{\arraystretch}{1.5} and so one... So i tried with the command \begin{sidewaystable} to rotate only the table. It doesn't work... I tried the whole tips on the remarked page before...

The target is to get this whole page on landscape format, but only this one! In my tried solutions the page before also was in landscape mode... I would approximate it, if you can give me some hints to find a solution for this problem, thank you! In the appendix is my code with some commented failed tries to reach this target and a picture how it looks!

Answer 1

"I tried with the command \begin{sidewaystable} to rotate only the table. It doesn't work..."

Perhaps this will help (I've added the figure version also).
