[F] Edit tables created using the QOwnNotes table tool

[fabianski7]

Expected behaviour

Enable the editing of created tables.

Current behaviour

It is possible to create tables very easily in QON, but you cannot use the same tool to edit them, even if they are created in QON itself.

Steps to reproduce

1. Create a table using the "Insert table" option
2. Try to edit it using the same option as the previous one

I think that would be quite some work and not really useful unless it also allows to add lines and columns and do other stuff as well...
