I'm standing on carpet flooring and I suspect that will produce static electricity overtime. Would a wood table and metal table have the same grounding properties as long as they are on the floor I'm standing on?
(1) Wood is not conductive. Carpet is not conductive in general (some carpets have metal threads woven in to reduce static.
Working on a Wood Table standing on carpet will not protect your gear and static could damage it.
(2) Metal table is fine. Make sure the metal table is grounded to your room ground (electrical ground). Attach a wire to the table and to the ground screw of an electrical outlet.
You can get a metal bracelet that you can attach to the table so when you work on your gear you and it will be safe.
You can also get a mat to stand on the will help control electrostatic discharge.
From your post, I assume you have the option of a wooden table (not at all conductive) and a metal table (will be conductive).
