@adkaikaitode,

Thanks for your inquiry. We suggest you please read following article.
Find and Replace

Following code example shows how to replace text with table. Hope this helps you.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Writeln("#TAB#");

FindReplaceOptions findOptions = new FindReplaceOptions();
findOptions.ReplacingCallback = new FindAndReplaceTag();

doc.Range.Replace("#TAB#", "", findOptions); 

doc.Save(MyDir + "output.docx");

public class FindAndReplaceTag : IReplacingCallback
{ 
    ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
    {
        // This is a Run node that contains either the beginning or the complete match.
        Node currentNode = e.MatchNode;
        Console.WriteLine(currentNode.GetText());

        // The first (and may be the only) run can contain text before the match, 
        // in this case it is necessary to split the run.
        if (e.MatchOffset > 0)
            currentNode = SplitRun((Run)currentNode, e.MatchOffset);

        ArrayList runs = new ArrayList();

        // Find all runs that contain parts of the match string.
        int remainingLength = e.Match.Value.Length;
        while (
            (remainingLength > 0) &&
            (currentNode != null) &&
            (currentNode.GetText().Length <= remainingLength))
        {
            runs.Add(currentNode);
            remainingLength = remainingLength - currentNode.GetText().Length;

            // Select the next Run node. 
            // Have to loop because there could be other nodes such as BookmarkStart etc.
            do
            {
                currentNode = currentNode.NextSibling;
            }
            while ((currentNode != null) && (currentNode.NodeType != NodeType.Run));
        }

        // Split the last run that contains the match if there is any text left.
        if ((currentNode != null) && (remainingLength > 0))
        {
            SplitRun((Run)currentNode, remainingLength);
            runs.Add(currentNode);
        }

                
        DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);

        //Move the cursor to the matched text and insert table
        builder.MoveTo((Run)runs[0]);

        Table table = builder.StartTable();

        // Insert a cell
        builder.InsertCell();
        builder.Write("This is row 1 cell 1");

        // Insert a cell
        builder.InsertCell();
        builder.Write("This is row 1 cell 2");

        builder.EndRow();

        // Insert a cell
        builder.InsertCell();
                 
        builder.Write("This is row 2 cell 1");

        // Insert a cell
        builder.InsertCell();
                 
        builder.Write("This is row 2 cell 2");

        builder.EndRow();

        builder.EndTable();

        // remove run nodes
        foreach (Run run in runs)
            run.Remove();

        // Signal to the replace engine to do nothing because we have already done all what we wanted.
        return ReplaceAction.Skip;
    }

    /// <summary>
    /// Splits text of the specified run into two runs.
    /// Inserts the new run just after the specified run.
    /// </summary>
    private static Run SplitRun(Run run, int position)
    {
        Run afterRun = (Run)run.Clone(true);
        afterRun.Text = run.Text.Substring(position);
        run.Text = run.Text.Substring(0, position);
        run.ParentNode.InsertAfter(afterRun, run);
        return afterRun;
    }
