How to create new columns in a SQLite File to add new data via DB Writer?

Dear Community,

I am a newbie with KNIME and want to create a SQLite File for metabase.

I did create an initial SQLite file and added data via DB Writer. Now I need to add additional columns in the existing table in the SQLite file and I struggle to add those. How do I do this? I would like to keep the old table as it is already binded to the docker container.

Any feedback is highly appreciated.
