<pre>private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            var tab = new Table();
            tab.Name = "MyTable";
            newRtb.RegisterName("MyTable", tab);


            var gridLenghtConvertor = new GridLengthConverter();

            tab.Columns.Add(new TableColumn() { Name = "Column1", Width = (GridLength)gridLenghtConvertor.ConvertFromString("*") });
            tab.Columns.Add(new TableColumn() { Name = "Column2", Width = (GridLength)gridLenghtConvertor.ConvertFromString("*") });

            tab.RowGroups.Add(new TableRowGroup());

            for (int i = 0; i < 10; i++)
            {
                tab.RowGroups[0].Rows.Add(new TableRow());
                var tabRow = tab.RowGroups[0].Rows[i];

                tabRow.Cells.Add(new TableCell(new Paragraph(new Run("Row" + (i + 1).ToString() + " Column1"))) { TextAlignment = TextAlignment.Center });
                tabRow.Cells.Add(new TableCell(new Paragraph(new Run("Row" + (i + 1).ToString() + " Column2"))));
            }


            newRtb.Document.Blocks.Add(tab);

        }






Table tab  = newRtb.FindName("MyTable") as Table;

            //add row:
            tab.RowGroups[0].Rows.Add(new TableRow());
            var tabRow = tab.RowGroups[0].Rows[tab.RowGroups[0].Rows.Count - 1];

            tabRow.Cells.Add(new TableCell(new Paragraph(new Run("NEW ROW C1"))) { TextAlignment = TextAlignment.Center });
            tabRow.Cells.Add(new TableCell(new Paragraph(new Run("NEW ROW C2"))));

            //remove first row:
            int index = 0;
            tab.RowGroups[0].Rows.RemoveAt(index);
