Parskip seems to reset after tabular environment

I am working on a document in which I include some tables. However, when I include the tables, the parskip length seems to reset to 0 afterwards. Why is that and how can I circumvent that?

The code I use with a small example is given in the following. Please note that I included every package I use for the sake of completeness. I do not know where the issue stems from exactly, so better include everything. So some packages are not required to display the following code per se.

The parskip option works fine before the table and is reset after it.
