Make it L-shaped and go deep into the underground cabinet, for example, make a cabinet of 1211 on one wall, and the cabinet on the other wall will block part of it, only part of it will be exposed, but in fact it is still connected. This is a better way to deal with it.

If there are columns, you can make it into a corner-cutting cabinet, and the table top can be opened on the spot, with a round hole and glass glue.
