The invention relates to a height-adjustable supporting frame preferably for a height-adjustable table comprising an upper frame with a longitudinal member (12) and a cross member (13), at least one lifting column (7) with telescopically arranged profiles, at least one foot (8). Where the lifting column (7) with a first end is secured to the upper frame and with a second end is secured to the foot (8), and where the longitudinal member (12) is designed as a cable tray. The longitudinal member thus forms a space which can be used as a cable tray, which from one side easily can be accessed and from the other side can hide the stored content.
