I copied the design/method from an article by Eric Keil in FWW #149. I had never thought of using biscuits this way. I used ps red oak rather than the qs white oak he used & milled mine to 7/8 vs. his at 1".
My photo is not the best. I dumbed it down for transmission & it lost a bit. The corbels barely show up, but they're there.
For those who don't get FWW, the top dimensions are 28X54" & the legs are 2.25"X29".
I'm thinking I may try the buscuit approach again.
