The invention belongs to the technical field of tables, in particular to a table with adjustable stability, comprising table legs, a driving device, a circular hole, a table plate, a hydraulic shell,a connecting rod, a limiting rod, a hydraulic plate, a first spring, a first square hole, a second square hole, a limiting block, a second spring, a push post and a hydraulic cavity. The invention also discloses a method of adjusting stability. When the floor on which the legs of the table are located collapses during use; the corresponding intermediate tube in the legs moves downward under the action of the third spring; Driving the corresponding three card blocks to move downward at the same time of moving; as that intermediate tube move one end of the distance; the upper end faces of the three card blocks move to the lower sides of the three limit blocks; and the intermediate tube between the ground and the legs will squeeze the intermediate tube upward after contacting with the intermediate tube; the intermediate tube moves upward; the intermediate pipe moves upward to drive the clamping block to move upward; the upper end face of the clamping block will contact with the similar limiting block in the moving process, so that that table is in a balance state.
