I do what has been recommend but have a piece of plywood cut to the size

That may not hurt, but unless the fit of plywood to table is airtight and
the plywood is sealed (and *not* with latex) I don't think it'll do any
good.

In some environments it may even trap moisture.

If it works for you, great. But I wouldn't suggest it as a general
solution.
