         9 . The height-adjustable sink of  claim 8 , wherein the sink table and the cooking table are adjusted in height independently of each other. 
     
     
         10 . The height-adjustable sink of  claim 8 , wherein the sink table comprises a lift plate and a sink bowl connected to the lift plate, and
 the height adjusting device is connected to the lift plate or the sink bowl.   
     
     
         11 . The height-adjustable sink of  claim 10 , further comprising a connecting member connected to the main body and the lift plate or connected to the main body and the sink bowl,
 wherein the connecting member comprises:   a first connecting member; and   a second connecting member extending in a direction crossing an extension direction of the first connecting member,   wherein an end portion of at least one of the first connecting member and the second connecting member is slidably coupled to one of the main body, the lift plate, or the sink bowl.   
     
     
         12 . The height-adjustable sink of  claim 11 , wherein the height adjusting device is connected to one of the first connecting member and the second connecting member and to the lift plate or the sink bowl, and the height adjusting device comprises a holding unit to maintain a height adjusted state. 
     
     
         13 . The height-adjustable sink of  claim 1 , wherein the upper plate comprises a fixed upper plate having a fixed height and a movable upper plate movably provided on the main body and adjustable in height,
 wherein the sink table is provided on one of the fixed upper plate and the movable upper plate, and the cooking table is provided on the other of the fixed upper plate and the movable upper plate.   
     
     
         14 . The height-adjustable sink of  claim 13 , wherein the fixed upper plate comprises a penetration portion, and
