just make the table top with a trim/lip around the edge where your pit mat would be and the mat can sit recessed, so when its dirty enough u can pull it out and hose it off or power wash it, or if its bad enough, throw it away and put in a new piece. then the piece wont slide around and it will look all finished and flush. i personally like a soft pit area so when i drop stuff it doesnt bounce and roll off instantly, atleast id have somewhat of a chance of finding it, lol.
Yeah I have the same thought about small screws and stuff rolling off. I do plan to run a piece of trim around the edge to help withthe roll offs but the bounces I had not thought of.
