Declaration:property NrOfColumns: longint;

The property NrOfColumns specifies the number of columns of the data structure.

Hint 1: Increasing the number of columns preserves all information in the table, while decreasing its number of columns destroys the information contained in the removed (rightmost) columns.

Hint 2: Increasing the number of columns requires considerably more computing time than decreasing it. Thus one should set or change the number of columns not too often.

Hint 3: In the Light Edition the max. number of cells of the data table is restricted to 2000 (i.e. the product of NrOfColumns times NrOfRows must not exceed 2000).
