A height-adjustable multifunctional table includes a base, at least two independent and height-adjustable table legs, a retaining frame, a tabletop, a power adapter, a controller, and a hand controller. Through the wireless connection between the hand controller and the controller, the controller is used to control a driving mechanism, and the driving mechanism drives a movable inner tube to move up and down so as to adjust the height of a tabletop. The user only needs to control the hand controller to adjust the height of the tabletop. The height adjustment is easy and more convenient and saves time and labour.
