Boy that's a hard one. I might be tempted to price out 1/4 inch plexiglass that could be cut the same shape as the tabletop? I have small white tiles with white grout on one section of my kitchen counter. I had a sheet of plexiglass(plastic) cut to cover it. Why you ask? I wanted a solid surface for rolling out pie dough and wanted an easy to sanitize surface for food preparation. This might be what they need or the table. It would protect it, be easy to clean and still let the beauty of the table show.
