jQuery实现为table表格动态添加或删除tr功能示例

<!-- 订单明细dialog -->
<div id="contractDetailDiv" title="销售订单明细" >
  <table class="exhibit_table" id="contractDetailTab" border="1">
    <tr>
      <td>订单合同号</td>
      <td colspan="4" id="orderId"></td>
    </tr>
    <tr>
      <td>捆包号</td>
      <td>品名</td>
      <td>规格</td>
      <td>材质</td>
      <td>重量</td>
    </tr>
  </table>
</div>
