What is the current background of the table?

Tenon and mortise structure. In the prior art, the table and its desktop structure are both tenon-mortise structures, which are characterized in that the expansion joints of the tenon-mortise structure are above the board surface, and because the falcon head is opened on the side surface and the falcon groove is opened at the same time, and then the table is spliced, so that the table is not beautiful, not firm enough, easy to accumulate dust, and the expansion groove is not easy to clean.
