stringgrid列着色时也标题也着没了,怎么办

哪图,标题本是单价和数量,着色是为了提示操作者这两条可以修改,但着色把标题也着没了,怎么办
代码如下
begin
if (ACol=7) or (ACol=8) then begin
StringGrid1.Canvas.Brush.color:=clcream;
StringGrid1.Canvas.FillRect(Rect);
end;


[解决办法]
不好意思，搞错了
if ((ACol=7) or (ACol=8))and (arow >0) then
begin
StringGrid1.Canvas.Brush.color:=clcream;
StringGrid1.Canvas.FillRect(Rect);
stringGrid1.canvas.TextOut(Rect.left+2,Rect.Top+2,stringgrid1.cells[ACol,ARow]);
end;
