Issue found:

• If you create a column, and then click to create rows, those rows never appear. Actually, the system creates those rows, but they are hidden from view until resizing the window. This may happen after this issue: https://bugreports.qt.io/browse/QDS-11762
• If you create multiple columns and delete them, you may not be able to select the column you created first. It may cause crash

• Snapshot: 43
• OS: Mac OS/ M1

Selecting columns and rows should be easy and it should not cause crash.
