Как передвинуть колонку в TDBGrid?

type
  THackAccess = class(TCustomGrid);

{
  THackAccess Is needed because TCustomGrid.MoveColumn is
  protected and you can't access it directly.
}

// In the implementation-Section:

procedure MoveDBGridColumns(DBGrid: TDBGrid; FromColumn, ToColumn: Integer);
begin
  THackAccess(DBGrid).MoveColumn(FromColumn, ToColumn);
end;


{Example}

procedure TForm1.Button1Click(Sender: TObject);
begin
  MoveDBGridColumns(DBGrid1, 1, 2)
end;
