Input Column Header Operators

A value in a truth-table input column header can be prefixed with one of the following operators: <, >, <=, >=, !=, \=, == . A column cell is evaluated by comparing its value with the column header value using the operator. The default operator is ==.

For example, a value of <X in an input column header causes a column cell with value Y to be evaluated as TRUE only when Y<X.
