ASP.NET前台点击按钮动态增加行
ASP.NET + C#:  
显示图如图
如图：上图为Table的一部分，我想当我点击上面的Add New Row按钮时在紧挨着此按钮的上面添加一行（点一次就添加一行，点多少次就添加多少行）。
前台的部分代码如下

            <tr>

                <th style="width:25%;">Version</th>

                        <td style="width:20%;text-align:center;"><asp:CheckBox ID="Driver_CheckBox" runat="server" /></td>
