在cxGrid的GridView属性设置事件onGridCustomDrawIndicatorCell，事件关键代码如下：

procedure TfrmHidden_Trouble.GridCustomDrawIndicatorCell(
  Sender: TcxGridTableView; ACanvas: TcxCanvas;
  AViewInfo: TcxCustomGridIndicatorItemViewInfo; var ADone: Boolean);
var
  AIndicatorViewInfo: TcxGridIndicatorRowItemViewInfo;
  ATextRect: TRect;
  aCV:TcxCanvas;
begin
  inherited;
  //======引用单元  cxLookAndFeelPainters
  if not (AViewInfo is TcxGridIndicatorRowItemViewInfo) then
    Exit;
  aCV:=ACanvas ;
  ATextRect := AViewInfo.ContentBounds;
  AIndicatorViewInfo := AViewInfo as TcxGridIndicatorRowItemViewInfo;
  InflateRect(ATextRect, -2, -1);
  Sender.LookAndFeelPainter.DrawHeader(ACanvas, AViewInfo.ContentBounds,
    ATextRect, [], cxBordersAll, cxbsNormal, taCenter, TcxAlignmentVert(vaCenter),
    False, False, IntToStr(AIndicatorViewInfo.GridRecord.Index + 1),
  acv.Font,acv.font.Color,acv.Brush.color );
  ADone := True;
end;
