Why doesnt air pressure crush an empty soft-drink can that is sitting on a table at your house?

Air pressure does exert force on the outside of the can, but it is balanced by the internal pressure within the can, which is the same as the atmospheric pressure when it is empty. As a result, there is no net force acting on the can to crush it. Additionally, the structural integrity of the can helps it maintain its shape against the external pressure. Thus, it remains intact while sitting on the table.
