It was a challenge to find a large enough protector for my 12'x4' outdoor dining table. This barely covered it but it works. It's not a very dense plastic.  I ended up stapling it with an electric stapler to the underside of the wooden table,  using some old playing cards to keep it from ripping the plastic. The table is left in the direct sun, with afternoon winds pretty consistent. So far, so good.  There is condensation under the cover in the mornings so if you have a good quality table, this situation wouldn't work.  I use sheets of plywood and any damage is minimal and not important to me. I just cover with a tablecloth when we use it.
