Re Earl's comment, I'm no expert on Shaker design, and most of the ones I've seen have been reproductions that have beveled edges, and even some with beading around the perimeters of drawers or aprons, for example.  On these, I did bevel the underside of the tabletop edge (~7 degrees) starting about 1/2" from the top, and then I rounded off the top 1/2" lip to soften it.   I did this because we have other "Shaker-Like" reproductions in the room where these are (bought years ago from some local furniture shop), and those pieces also have a similar beveled edge.
