请教怎么取得Div下的 Table 对象(Table没有ID) _JavaScript

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.

补充一下,就是想让表格中的每行根据"完成"/"执行中"这两种不同的状态改变颜色.

再次拜谢

------解决方案--------------------
div id 知道吗？如果最外层的div id知道就好办了，
使用
var tbl = document.getElementById("outtest div ID").childNodes[0].childNodes[0];
可以取得table对象
改变table行的颜色，通过改变i行的样式实现的代码是
tbl.rows[i].className = "行的className";
