 =====Description=====
 This action calculates one or more new columns using [[syntax:start|expression(s)]]. One expression creates one column.
-The expression is calculated for every row. Other column values in the same row can be referred to by column names in square brackets. It's not possible to refer from one row to another row or to another table.
-Instead of an expression, this action can insert a full column of static text or numeric values.\\
