cxGrid顯示行號

定義一個類：

TMyCxGrid =   //method === (AViewInfo  TcxGridIndicatorHeaderItemViewInfo) 
  =-, -=  (AViewInfo  TcxGridIndicatorRowItemViewInfo) == AViewInfo -, - AIndicatorViewInfo.GridRecord.Selected = ACanvas.Font.Style += ACanvas.Font.Style -+ =;

然後調用即可：

tvList.OptionsView.Indicator:=== TMyCxGrid.DrawIndicatorCell;

測試GridMode顯示有問題。
