Making the table structure vsible

[smallbrownfrog]

This is probably an incredibly basic question, but could somebody please help me understand how to make a Work Skin that will make all the dividing lines in a table visible again? I have a meta piece that I want to post, but it's completely unreadable and unusable once AO3's software has removed all the borders. I need clear lines between the different table cells so that people can easily scan a column or row.

Thank you.
