这个水平有限，各位哥哥帮我注释一下啊，感激不尽。。后边还有一些，还得有劳各位，越详细越好，我是菜鸟

procedure TForm1.cxGrid4DBTableView1CustomDrawIndicatorCell(
  Sender: TcxGridTableView; ACanvas: TcxCanvas;
  AViewInfo: TcxCustomGridIndicatorItemViewInfo; var ADone: Boolean);
var
  AIndicatorViewInfo: TcxGridIndicatorRowItemViewInfo;
  ATextRect: TRect;
  AStyle: TcxStyle;
begin
  if not (AViewInfo is TcxGridIndicatorRowItemViewInfo) then
    Exit;
  ATextRect := AViewInfo.ContentBounds;
  AIndicatorViewInfo := AViewInfo as TcxGridIndicatorRowItemViewInfo;
  InflateRect(ATextRect, -2, -1);
  if AIndicatorViewInfo.GridRecord.Selected then
    AStyle := styleSelected
  else
    AStyle := styleNormal;
  Sender.LookAndFeelPainter.DrawHeader(ACanvas, AViewInfo.ContentBounds,
    ATextRect, [], cxBordersAll, cxbsNormal, taCenter, vaCenter,
    False, False, IntToStr(AIndicatorViewInfo.GridRecord.Index + 1),
    AStyle.Font, AStyle.TextColor, AStyle.Color);
  ADone := True;
end;
