修改GRID.pas
view plaincopy to clipboardprint?
//在TCustomGrid.SetColWidths事件改为:
procedure TCustomGrid.SetColWidths(Index: Longint; Value: Integer);
begin
if FColWidths = nil then
UpdateExtents(FColWidths, ColCount, DefaultColWidth);
if Index >= ColCount then InvalidOp(SIndexOutOfRange);
if Value <> PIntArray(FColWidths)^[Index + 1] then

if Value < 12 then Value := 30; //新增
ResizeCol(Index, PIntArray(FColWidths)^[Index + 1], Value);
PIntArray(FColWidths)^[Index + 1] := Value;
ColWidthsChanged;

修改DBGRID.pas
view plaincopy to clipboardprint?
//在procedure TCustomDBGrid.DrawCell事件中找到下面这一行
procedure TCustomDBGrid.DrawCell(ACol, ARow: Longint; ARect: TRect; AState: TGridDrawState);
begin
//...
FIndicators.Draw(Canvas, ALeft,
(ARect.Top + ARect.Bottom - FIndicators.Height) shr 1, Indicator, True);
if ACol <0 then
begin
Canvas.TextRect(ARect,0,(ARect.Top + ARect.Bottom - FIndicators.Height) shr 1 , inttostr(self.DataSource.DataSet.RecNo));
end; //新增
//.....
end;
