Column Comparator

Compares the cell values of two selected columns row-wise. A number of different comparison methods are available: equal, not_equal, less, greater, less_equal, and greater_equal. A new column is appended holding either the left or right column value, a missing cell, or a user specified tag. The type of the appended column depends on the selected content: If a user defined tag is selected, the result column is of type string, in all other case the type is determined by the type of the selected columns.
