NrOfColumns


Unit:SDL_datatable
Class: TDataTable
Declaration: property NrOfColumns: longint;

The property NrOfColumns specifies the number of columns of the data table. Changing the number of columns triggers the OnResize event.

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: In the Light Edition the number of cells is restricted to 2000 (NrOfColumns times NrOfRows).

Example: This property is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): simplepca
