The table includes a substantially horizontal base and a substantially horizontal frame disposed above the base, with a plurality of adjustable-length support posts disposed between the base and the frame, one end of each support post being affixed to the base and the other end of each support post being affixed to the frame. Post lock pins on each of the plurality of support posts selectively lock each support post at a selected length. A table top disposed above and supported by the frame is attached to the frame by a hinge. A table lock selectively locks the table top to the frame to prevent tilting of the table about the hinge. A hydraulic lift cylinder is dipsosed between and connected to the table top and the base for lifting the table top relative to the base. The left cylinder can raise the table top and the frame together when the table lock is locked and each of the post lock pins is unlocked, and the lift cylinder can tilt the table top about the hinge without raising the frame when the table lock is unlocked and each of the post locks is locked.
