Hello, David,
Move your mouse to the column you want to delete and right click to select the column, or columns. They should turn gray. Then select "Delete" from the option window than appears and choose columns. They'll disappear as quickly as a stimulus check.
You can also add columns or rows with this technique.

You have the option of deleting only the cell selected. When you right click on it, an option box pops up to which you select the desired outcome.01/21/21
