Abstract: A work table assembly includes a table that may be positioned on a support surface. An object, such as lumber or the like, is selectively positioned on the table for cutting and otherwise manipulating. A plurality of extension units is provided and each of the extension units is slidably coupled to the table. Each of the extension units is selectively positioned in a deployed position to support an object that is larger than the table. Each of the extension units is selectively positioned in a stored position. A plurality of panels is provided and each of the panels is selectively positioned on the table to define a horizontal support surface.
