A unique foldable table comprises a collapse-preventing tabletop assembly, a plurality of extendable-leg assemblies releasably attached to the tabletop assembly, and a plurality of scissoring-arm assemblies attached to the extendable-leg assemblies, respectively. The collapse-preventing tabletop assembly has an automatic collapse-preventing system of clamps for automatically cross-interlocking the tabletop and the extendable-leg assemblies to prevent the unique foldable table from folding inwards and collapsing. The extendable-leg assemblies have: an automatic button-latching and button-releasing system of spring-loaded latches for automatically latching and automatically releasing the release buttons to simplify the cumbersome, two-handed table operation into an easy, one-handed table operation to eliminate the risk of personal injury; and an automatic leg-centering system of leg-centering clamps for automatically centering and clamping the extendable-leg assemblies to lock them in place.
