A height-adjustable table with a stop control system includes a tabletop, a table leg, a power supply, a lifting module, a sensing module, a sound module, a main control unit, and a manual controller. Through the design of the sensing module and the main control unit, when a person or an object is approaching during the descent of the tabletop, the sensing module feeds back the received signal to the main control unit and controls the lifting module to stop running. The structural design is clever and reasonable, easy to use, practical, and can be widely used.
