// Open the existing Word document using a FileStream.
using (FileStream docStream = new FileStream(Path.GetFullPath(@"../../../Data/InputDocument.docx"), FileMode.Open, FileAccess.Read))
{
   // Load the existing Word document.
   using (WordDocument document = new WordDocument(docStream, FormatType.Docx))
   {
       // Find the first sequence field (SEQ field) in the document.
       WSeqField seqField = document.FindItemByProperty(EntityType.SeqField, "", "") as WSeqField;
       // Get the paragraph that contains the SEQ field.
       WParagraph paragraph = seqField.OwnerParagraph;
       // Get the index of the paragraph within the text body.
       int paraindex = paragraph.OwnerTextBody.ChildEntities.IndexOf(paragraph);
       // Get the index of the SEQ field within the paragraph.
       int seqfieldIndex = paragraph.ChildEntities.IndexOf(seqField);
       // Clone the paragraph that contains the SEQ field.
       WParagraph clonedParagraph = seqField.OwnerParagraph.Clone() as WParagraph;
       // Remove all entities before the SEQ field index in the cloned paragraph.
       for (int i = seqfieldIndex; i >= 0; i--)
       {
           clonedParagraph.ChildEntities.RemoveAt(i);
       }
       // Remove all entities from the SEQ field index onward in the original paragraph.
       for (int j = paragraph.ChildEntities.Count - 1; j >= seqfieldIndex; j--)
       {
           paragraph.ChildEntities.RemoveAt(j);
       }

       //Create a new table
       IWTable table = new WTable(document);
       table.ResetCells(3, 2);
       table.Rows[0].Cells[0].AddParagraph().AppendText("Sno");
       table.Rows[0].Cells[1].AddParagraph().AppendText("Product");
       table.Rows[0].IsHeader = true;
       table.Rows[1].Cells[0].AddParagraph().AppendText("1.");
       table.Rows[1].Cells[1].AddParagraph().AppendText("Essential DocIO");
       table.Rows[2].Cells[0].AddParagraph().AppendText("2.");
       table.Rows[2].Cells[1].AddParagraph().AppendText("Essential Pdf");

       // Clone the generated table.
       IWTable table1 = table.Clone() as IWTable;
       // Insert the cloned table after the paragraph containing the SEQ field.
       paragraph.OwnerTextBody.ChildEntities.Insert(paraindex + 1, table1);
       // Insert the modified cloned paragraph after the inserted table.
       paragraph.OwnerTextBody.ChildEntities.Insert(paraindex + 2, clonedParagraph);
       // Save the modified document to a new file.
       using (FileStream docStream1 = new FileStream(Path.GetFullPath(@"../../../Data/ResultDocument.docx"), FileMode.Create, FileAccess.Write))
       {
           document.Save(docStream1, FormatType.Docx);
       }
   }
}
