关于DBGridEh v4.4.31合计行的网格填充的实现，请大家帮帮我

以下代码在4.3.21下还是有效的，当DBGridEh存在合计行时，就会自动填充空白的网格，可是到了v4.4.31就没有用了，那个高人能帮我改一下，让这个填充空白的代码能用呢！谢谢大家了！！
在2162行增加一下内容：
      //ljb at 2008-12-12 begin      if (DrawInfo.Vert.ContraCelCount > 0) then
      begin
        DrawLines(DrawInfo, goFixedHorzLine in Options, goFixedVertLine in Options,
          0, TopRow, [0, Vert.FixedBoundary, Horz.NoFrozenBoundary, Vert.FullGridBoundary {Vert.GridBoundary}],
          GridLineColors.GetCellColor(0, TopRow) {FFixedLineColor}, FixedColor, Canvas, DrawLinesInfo);        if Horz.FrozenCelCount > 0 then
        begin
          DrawLines(DrawInfo, goFixedHorzLine in Options, goFixedVertLine in Options,
            FixedCols - FrozenColCount, TopRow,
            [Horz.NoFrozenBoundary, Vert.FixedBoundary, Horz.FixedBoundary - 1, Vert.FullGridBoundary {Vert.GridBoundary}],
            GridLineColors.GetCellColor(FixedCols - FrozenColCount, TopRow) {LineColor}, FixedColor, Canvas, DrawLinesInfo);
          DrawOneLine(Horz.FixedBoundary - 1, Vert.FixedBoundary,
            Horz.FixedBoundary - 1, Vert.FullGridBoundary {Vert.GridBoundary},
            GridLineColors.GetRightBorderCellColor(FixedCols - 1, TopRow));
        end;
        RCR := SetDataDrawOriginClipRegion(
          Horz.FixedBoundary, Vert.FixedBoundary, Horz.GridBoundary, Vert.NoFrozenBoundary);        DrawLines(DrawInfo, goHorzLine in Options, goVertLine in Options, LeftCol, TopRow,
          [Horz.FixedBoundary, Vert.FixedBoundary, Horz.GridBoundary, Vert.FullGridBoundary {Vert.GridBoundary}],
          GridLineColors.GetCellColor(LeftCol, TopRow) {LineColor}, Color, Canvas, DrawLinesInfo);      end;
      //ljb at 2008-12-12 end
