A table may include a table top and one or more legs and the legs may be movable between an extended or use position and a collapsed or storage position. The table may include one or more cross bars and the legs may be attached to the cross bars. The table may also include a frame and the frame may include one or more side rails. The cross bars may be sized and configured to engage at least a portion of the table frame with a generally rigid connection when the legs are in the extended position and a loose connection with the legs are in the collapsed position. In addition, the table may include one or more connecting members that may be disposed towards the ends of the table. Advantageously, the connecting members and/or cross bars may securely support the table top and help prevent the table top from undesirably twisting or deforming if a load or force is applied to a portion of the table top.
