How can I hide admin columns showing extra custom taxonomy fields?

After looking at the class names assigned to the and table columns, I set a “display: none;” CSS rule to all the extra columns with the class names of the extra custom taxonomy fields that I added. Not the most sophisticated solution if you have a lot of extra custom fields like I do, but it does the job.
