pls have a look at this issue:
https://bugs.documentfoundation.org/show_bug.cgi?id=107541
since version 5.3.1 and with 5.3.2.2 I can not edit tables anymore.
I would like to delete my userprofile, if that might be the reason.
pls inform, where it is located (similar to %appdata%\Roaming\LibreOffice\4\user in full installation)
