Definition:Truth Table

Definition
A truth table is a tabular array that represents the computation of a truth function, that is, a function of the form:
 * $f : \mathbb B^k \to \mathbb B$

where:
 * $k$ is a non-negative integer
 * $\mathbb B$ is a set of truth values, usually $\left\{{0, 1}\right\}$ or $\left\{{T, F}\right\}$.

Structure
Truth tables are constructed of rows and columns.
