Hi nikitha.P,

Thanks for posting in the MSDN Forum.

This is a simple sample for your goal, you are able to extend it by yourself. Please omit the comment, it just the track of my work.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;
//using log4net;
//using MyLog4Net;
using System.Windows.Forms;
using System.IO;

namespace ConsoleApplication23
{
    class Program
    {
        //private static ILog log = MyLog4Net.MyLog4Net
        //    .Generator1(AppDomain.CurrentDomain.BaseDirectory + "Logger.log", 
        //    typeof(Program), "DEBUG", true);

        [STAThread]
        static void Main(string[] args)
        {
            OpenFileDialog ofd = new OpenFileDialog();
            ofd.Multiselect = false;
            ofd.Filter = "Word Document|*.docx";
            ofd.ShowDialog();
            string original = ofd.FileName;
            //log.Info("Original Document : " + original);
            string basepath = AppDomain.CurrentDomain.BaseDirectory;
            string target = basepath + "Test.docx";
            //log.Info("Target Document : " + target);
            File.Copy(original, target, true);
            //log.Info("File Copied");
            using (WordprocessingDocument wpd = WordprocessingDocument
                .Open(target, true))
            {
                //log.Info("Document has been opened");
                MainDocumentPart mdp = wpd.MainDocumentPart;
                //log.Info("Get Main Document part.");
                Document d = mdp.Document;
                Table table = d.Descendants<Table>().FirstOrDefault();
                //log.Info("Get first table");
                TableRow tr = table.Descendants<TableRow>().ToList()[1];
                //log.Info("Get Second row of the table");
                TableCell td = tr.Descendants<TableCell>().ToList()[2];
                //log.Info("Get Third column of the table row");
                Paragraph tc = td.Descendants<Paragraph>().FirstOrDefault();
                if (tc == null)
                {
                    tc = new Paragraph();
                    td.Append(tc);
                    //log.Info("Append Paragraph");
                }
                else
                {
                    //log.Info("Get the content of the table cell");
                    Run r = new Run();
                    Text text = new Text();
                    text.Text = "I will append some content in here!";
                    r.Append(text);
                    tc.Append(r);
                    //log.Info("Update table information");
                }
                d.Save();
                //log.Info("Document has been saved");
            }
            Console.ReadKey();
        }
    }
}
