A compound. As a solid, table salt consists of sodium cations (Na+) and chlorine anions (Cl-) which are arranged into a giant ionic lattice structure (which is held in place by the electrostatic attraction between the opposite charges on the ions) - the structure does not conduct electricity.
In solution, this structure is lost as the salt dissolves; the oppositely charged ions are free to move about and pass each other, enabling the solution to conduct electricity.
I would say that in solution or in a 'mixture' - depending on whether it is saturated, that it is a homogenous mixture as there is no physical difference in the state of the components of the mixture.

Table Salt is a compound made of the elements Sodium and Chlorine. This makes up the compound: NaCl (commonly known as table salt.)
Table salt is a (pure) substance, chemically named: sodium chloride, NaCl. Though it is certainly 'homogeneous' (pure solid crystal), it is neither a mixture nor heterogenous.
