Proposal

There should be an option to remove the thick glaring dark bottom border from thead and top border from tfoot in the table element.

Motivation and context

Not everybody will like this. I have updated a big project (which has hundreds of tables) to bootstrap 5.1.3. Now I need to remove the thick glaring dark bottom broder from thead and the top border from tfoot in the table element.

Right now, how can I remove these borders using custom CSS? Please help me.
