identifying names of tables for CSS

Is there somewhere that tells us all the table names to use when using CSS?
Specifically for now, I'm trying to modify what shows using printer-friendly generated from Group Order, or does that just use the same table as the group order itself?
I was hoping to have some columns still show in Group Order, but not when printing
Thanks for any help
