Abstract: An extendable table includes a table support, a table top which is movable relative to the table support, a table leaf, a guiding unit, and a guided bar. The table leaf is displaceable between a normal position, where the table leaf is disposed under the table top, and an extended position, where the table leaf is substantially coplanar with the table top. When the table top is lifted, the table leaf is permitted to be displaced from the extended position to the normal position.
