如何在DBGrid中选择多个单元格，并在StatusBar中显示选中单元格的和
如题，请指教！

[解决办法]
The following example copies the selected rows in a db grid to a list box.

procedure TForm1.Button1Click(Sender: TObject);
var
i, j: Integer;
s: string;
begin
if DBGrid1.SelectedRows.Count> 0 then
with DBGrid1.DataSource.DataSet do
for i:=0 to DBGrid1.SelectedRows.Count-1 do
begin
GotoBookmark(pointer(DBGrid1.SelectedRows.Items[i]));
for j := 0 to FieldCount-1 do
begin

if (j> 0) then s:=s+ ', ';
s:=s+Fields[j].AsString;
end;
Listbox1.Items.Add(s);
s:= ' ';
end;
end;
是不是要这,改一改就成求和的了
