I can't change the range of my table

Hi,

I have a defined table with defined columns. The defined table stretches out to the last rows in the sheet while it should only cover the cells that contain values. I would like to reselect the range but this is somehow not possible. The "delete" button is also greyed out.

How can i solve this problem?

Any input is much appreciated!

I checked an earlier post on this site with the same question. This is the answer that was given:

1. Select the table
2. On the Table Tools Menubar > Design > Tools
Select Convert to Range

It works!
