 The following code will generate table cells as needed and add it in panel for further requirement.

 public void generateoption()
    {
        bool isImage = rblOptionsType.SelectedIndex == 1;
        int rowCount = 4;
        Table table = new Table();

        table.ID = "tblOptionsCollection";
        for (int i = 0; i < rowCount; i++)
        {
            TableRow row = new TableRow();
            TableCell cell5 = new TableCell();
            cell5.Width = 150;
            cell5.ID = "cell5" + i.ToString();
            cell5.Text = "      ";
            row.Cells.Add(cell5);

            TableCell cell1 = new TableCell();
            cell1.Width = 300;
            cell1.ID = "cell1" + i.ToString();
            cell1.CssClass = "h_text";
            cell1.Text = "Option :" + (i + 1).ToString();
            row.Cells.Add(cell1);

            if (!isImage)
            {
                TableCell cell = new TableCell();
                TextBox TxtBoxU = new TextBox();
               
                TxtBoxU.TextMode = TextBoxMode.MultiLine;
                TxtBoxU.Width = 300;
                TxtBoxU.Text = "";
                TxtBoxU.ID = "TextBoxU" + i.ToString();
                cell.ID = "cell" + i.ToString();
                cell.Controls.Add(TxtBoxU);
                row.Cells.Add(cell);
            }
            else
            {
                TableCell cell = new TableCell();
                FileUpload fileUploadOption = new FileUpload();
                fileUploadOption.Width = 300;
                fileUploadOption.ID = "fileUploadOption" + i.ToString();
                cell.ID = "cell" + i.ToString();
                cell.Controls.Add(fileUploadOption);
                row.Cells.Add(cell);
            }
            TableCell cell11 = new TableCell();
            cell11.ID = "cell11" + i.ToString();
            cell11.Text = "";
            row.Cells.Add(cell11);

            table.Rows.Add(row);
        }
        Panel1.Controls.Add(table);
    }
