What about covering the wood with a table pad and putting the cover on over that?

My concern is this. They want a moisture-proof cover. Granted that a moisture-proof cover prevents liquids from touching the wood. The problem is they also trap moisture. Unless the room is very dry, I would be concerned about condensation underneath the moisture-proof covering, which would trap moisture inside the cover. And, as we all know, moisture damages wood.
I think any type of moisture-proof covering would need to be removed regularly (at least weekly), allowing any trapped moisture to escape.
