Getting Started:

Hide a column by setting the visibility of the column to false using the setColumnVisible method.
This will hide columns B through:

activeSheet.setColumnVisible(1, false, GC.Spread.Sheets.SheetArea.viewport);
activeSheet.setColumnVisible(2, false, GC.Spread.Sheets.SheetArea.viewport);
activeSheet.setColumnVisible(3, false);

activeSheet.setRowVisibility(5, false, GC.Spread.Sheets.SheetArea.viewport);
activeSheet.setRowVisibility(6, false);
