Creating arrow-sourcable table rows in Draw.io

Question

I'm trying to create a three column table in draw.io. I've started with the software / entity relationship example and adapted the style slightly. I've taken this example because I need my arrows to originate and go to specific rows in the table, and not just the table in general.

However, I have a few problems, I'm at a loss on how to create a third column, I would like for the vertical line to extend all the way down even if the elements don't (currently they are a right-line on the left inside element of the "row"). And finally, I need to be able to adapt the size of the columns flexibly (rather than having to edit settings in the individual rows). Am I missing a better solution here?

I am not sure I Understood all details, but this article might help: https://drawio-app.com/tables-in-drawio-got-a-makeover/

You can make something like this and modify it additionally.

or just copy/paste this code to Extras > Edit diagram
