将Word doc转换为pdf-在表格上获取空白单元格（服务器端）

Question

所以下面的这段代码可以正常工作，可以完成工作-word-> PDF。

只有一个问题，当单词doc的表中包含有单元格时，将单词doc转换为pdf时，pdf会显示单元格合并但内部没有值。

有人知道为什么吗？有什么解决办法吗？

注意：这是在服务器端进行的转换。

  if (nomeDocTemplate == attachment)
                                {
                                    web.AllowUnsafeUpdates = true;
                                    string wordEdit =item2.Attachments.UrlPrefix + "Template" + item.ID + ".docx";
                                    string wordAutomationServiceName = "Word Automation Services";
                                    string filenamedest = web.Url + item.File.ServerRelativeUrl;
                                    SPFile attachmentFile = item2.Web.GetFile(wordEdit);

                                    using (MemoryStream destinationStream = new MemoryStream())
                                    {

                                        //Call the syncConverter class, passing in the name of the Word Automation Service for your Farm.                             

                                        SyncConverter sc = new SyncConverter(wordAutomationServiceName);

                                        ////Pass in your User Token or credentials under which this conversion job is executed.
                                        sc.UserToken = SPContext.Current.Site.UserToken;
                                        sc.Settings.UpdateFields = true;
                                        //Save format
                                        sc.Settings.OutputFormat = SaveFormat.PDF;


                                        ////Convert to PDF by opening the file stream, and then converting to the destination memory stream.
                                        ConversionItemInfo info = sc.Convert(attachmentFile.OpenBinaryStream(), destinationStream);

                                        var filename = Path.GetFileNameWithoutExtension(item.File.Name) + ".pdf";

                                        if (info.Succeeded)
                                        {
                                            //File conversion successful, then add the memory stream to the SharePoint list.
                                            SPFile newfile = web.Lists["Tramitar"].RootFolder.Files.Add(filename, destinationStream, true);

                                        }
                                        else if (info.Failed)
                                        {
                                            throw new Exception(info.ErrorMessage);
                                        }



                                    }

                                    //ConcatAndAddContent(anexosProcesso);

                                    return;
                                }
