Abstract: A table adapted for attachment to an external support, e.g., the trunk latch of a motor vehicle. In a preferred embodiment, the table of the present disclosure comprises a portable folding table attachable at one end to the trunk latch of an automobile, minivan or sport utility vehicle and supported at the other end by a pair of foldable, independently telescopically adjustable legs. The tabletop comprises two panels hingedly attached to one another along adjacent transverse edges. A novel adaptor is provided for attaching one of the panels to the locking mechanism of the trunk latch of the vehicle. The portable folding table folds for storage or transportation. The panels are provided with downwardly extending edges which, when the table is folded, form a space into which the adjustable legs may be folded.
