An extensible table with its unextended tabletop formed by leaves that are slidably fixed on the supporting frame of the table. The sliding leaves are moved away from each other to reveal a hidden extension leaf that is raised by momentarily applying an initiating downward force. The extension leaf raises itself to the same level as the sliding leaves are to form an extended tabletop. The extension leaf is moved down to its original level by an applied downward force and allows for the sliding leaves to be slid toward each other to form the unextended tabletop. Latching is accomplished by a latching pin. The first end of the latching pin is in a pin housing. This allows the second end of the latching pin to move in the groove of the grooved block. A spring in the pin housing holds the second end of the pin in the grove.
