Column types determine how column data can be sorted and displayed. By default, column data is treated as a text string, and thus, can be sorted automatically when a column heading is clicked. CSV macros may automatically generate more precise column types. When the default behavior is less than optimal for your situation, the Column types parameter can be set specifically.

Numeric types are right-aligned, by default. To display the totals of any numeric column(s), you must specify the relevant numeric type for the required columns in Column types, and enable the Auto total row option.

This table describes the behavior of the various types.
