You have to save it to a file or memory stream and then push the file to Sharepoint (however that's done).

I attempt, but not change file "testnew.xlsx"

  SPFile spfile = web.GetFile("http://localhost/Deps/SUP/Shared Documents/testnew.xlsx");
                                    if (spfile.Exists)
                                        byte[] byteArray = spfile.OpenBinary(); 
                                        MemoryStream _stream = new MemoryStream();
                                        _stream.Position = _stream.Length;
                                        _stream.Write(byteArray, 0, byteArray.Length);
                                        var workbook = new XLWorkbook(_stream);
                                        IXLWorksheet sheet = workbook.Worksheets.Add("New Worksheet");

I have no idea what any of this means but this library doesn't understand Sharepoint. You have to get the file from Sharepoint (however that's done, I can't tell you) and then modify it with ClosedXML, and finally update the file on Sharepoint (however that's done, once again I can't tell you how, you have to figure that out).
