               TextBodyPart bodyPart = new TextBodyPart(document);
               //Add the table to the body part.
               bodyPart.BodyItems.Add(table);
               //Replace the placeholder text with the HTML table in the Word document.
               document.Replace("<<Product Table>>", bodyPart, true, true, false);
               //Create a file stream to save the modified Word document.

               {
                   //Save the modified Word document to the file stream.
