Abstract
A display table used in exhibition sights, etc. including a table top and four foldable legs attached to the table top. The upper ends of the legs can slide along the side edges of the table and between the center and the corners of the table top. By sliding the legs and thus changing the angles between the legs and table top, the height of the table is changed. At a desired height, the legs are secured to the table top via bolts.
