The subtable restricts an existing table to those lines that fulfil a specified condition (= formula).

Example: A simple condition could be a >= 10. This condition must be assigned to a certain column of the master table. Then the subtable contains only rows with values >= 10 in the requested column. The master table remains unchanged.

After entering the formula string the arguments are requested via the text area. They are explicit parameters that have to be entered in combination (list parameters).

Attention: At least one argument must refer to a column name.
