请问如何取得Div下的 Table 对象(Table没有ID)

<div class='view view-case-view-all'>
  <div class='view-content view-content-case-view-all'>
    <table border="1">
      <tr class="odd">
        <td class="view-field view-field-node-title">任务测试1</td>
<td class="view-field view-field-workflow-states-state">执行中</td>
      </tr>
      <tr class="even">
        <td class="view-field view-field-node-title">任务测试2</td>
<td class="view-field view-field-workflow-states-state">完成</td>
      </tr>
      <tr class="even">
        <td class="view-field view-field-node-title">任务测试3</td>
<td class="view-field view-field-workflow-states-state">执行中</td>
      </tr>
    </table>
  </div>
</div>请问如何根据 table 中每行 第二个TD中的内容控制表格行的颜色?
主要的困难是Table 没有ID.不知如何取得Table 对象拜谢各位了.
