If you mean glue up in modules, no, I glue everything at one time.

The web frame approach is a recommended way to proceed if that is the look one wants on the back of the table, back being opposite drawers. Not the look I chose for this piece.

A web with a dovetail end, another web double tenon and the panel mortised all perfectly inserted into a leg is a daunting challenge to accomplish without any gap at any of the shoulders. I did that once, but not thereafter.
