6.1.1 addcol

Usage:

   addcol [-after <col-id> | -before <col-id>]
          [-units <units>] [-ucd <ucd>] [-utype <utype>] [-desc <descrip>]
          <col-name> <expr>

Add a new column called <col-name> defined by the algebraic expression <expr>. By default the new column appears after the last column of the table, but you can position it either before or after a specified column using the -before or -after flags respectively. The -units, -ucd -utype and -desc flags can be used to define metadata values for the new column.

Syntax for the <expr> and <col-id> arguments is described in the manual.
