A honeycomb tabletop (11), has a honeycomb core (21) positioned between a top (13) and bottom (15) structural layer. A number of cups (25) are positioned between the bottom layer (15) and the top layer (13), and at least some of the number of cups (25) are sized and shaped to cooperate with the lower face (59) of the top layer (13) to form a cavity surrounding at least two of the plurality of holes (19) in the top layer (13) so that contaminants will be unable to pass through the surrounded holes (19) into the honeycomb core (21). These cups (25) form a sealing engagement with the lower face (59) of the top layer (13) to facilitate rapid and thorough cleaning of contaminants from the cups (25). <IMAGE> <IMAGE>
