The invention relates to a working method of a workbench capable of automatically adjusting the levelness. At least three height-adjustable supporting leg assemblies used for supporting a workbench top are included. Each supporting leg assembly comprises an upper supporting leg, a lower supporting leg and a lifting mechanism arranged between the upper supporting leg and the lower supporting leg. A hydraulic inlet and a hydraulic outlet are formed in the side face of a cylinder body and a cylinder cover of each lifting mechanism respectively, wherein the hydraulic inlet and the hydraulic outlet are connected with a hydraulic pump through a hydraulic pipeline. The lower end face of the workbench top is provided with a double-axis horizontal sensor which is connected with a processor unit. The processor unit is used for controlling through holes in the lifting mechanisms to be opened, a medium flows to the lower portions of piston body assemblies in the lifting mechanisms from the upper portions of the piston body assemblies, and the cylinder bodies are made to move downwards to reduce the height of the corresponding upper supporting legs; or the through holes are closed, the hydraulic pump is started, the medium is made to flow to the upper portions of the piston body assemblies from the lower portions of the piston body assemblies through the hydraulic pipeline, and the cylinder bodies are made to move upwards to increase the height of the corresponding upper supporting legs till the workbench top is level.
