  if column=Griddg.Columns[5] then   Griddg.Canvas.TextOut(Rect.left, Rect.top, '555')

不要单步调试，这样不一定行，可能要重载

Answer 1

procedure ttt.GridDGDrawColumnCell(Sender: TObject; const Rect: TRect;
  DataCol: Integer; Column: TColumnEh; State: TGridDrawState);
begin
  if column=Griddg.Columns[5] then   Griddg.Canvas.TextOut(Rect.left, Rect.top, '555');
  DBGrid1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
 //加上这句；
end;

Answer 2

if column=Griddg.Columns[5] then   
好象有问题
试试
if column=5 then
