Abstract: An improved table attachment for removably mounting and rotatably mounting an attachment on a conventional table having either vertical or non-vertical legs. The improved table attachment includes a base having a top surface and a bottom surface, a support member is attached to the bottom surface of the base approximately across the centerline of the base. The support member includes a front and rear side wherein the support member defines a top elongate longitudinal threaded hole having an opening in the front side and a bottom longitudinal hole lower than the first hole and approximately parallel to it having an opening in the front side and extending through to the rear side of the support member. Structure for connecting the portable table attachment to a conventional table leg engage the top and bottom longitudinal holes and the table leg in such a manner that the table attachment is supported by the table leg and the attachment is able to rotate a limited distance laterally.
