A telescopic and foldable table comprises a table frame having two supporting posts at two sides thereof; each post having a liftable inner tube; each post being installed to a transversal leg at a bottom end thereof; an upper end of the inner tube of the post having a pivotal unit which is pivotally installed to the table plane so that the table plane can pivotally move or transversally displace. By above mentioned components, the table is telescopic and foldable. Each post has a plurality of openings for determining the elevation of the post; each inner tube has a telescopic buckle and a control rod for controlling the telescopic movement of the buckle; and the control rod is controlled by a control unit protruding out of the inner tube. The pivotal unit is pivotally installed to a pivotal seat at a bottom surface of the table plane.
