A linked structure for foldable table comprises a main frame, legs, props, connecting plate 1 and connecting plate 2. The main frame includes a plate body which connects multiple table plates with flexible wire on each side of the plate body. Each concave body and supporting leg is set under each end of the plate body. A connecting unit with a receiving concave is set in the concave body. The legs are set in the receiving concave of the connecting unit. Connecting plate 1 is set on the props on the connecting unit. Connecting plate 2 which set on the legs connects with connecting plate 1. The table plates are connected on each side of the plate body on main frame with flexible wire. When folding the present invention, the legs, props, connecting plate 1 and 2 are folded under the plate body through rotating the connecting unit.
