<table>

<tbody id="tb-37327761306">

<tr class="sep-row"><td colspan="5"></td></tr>
<tr class="tr-th">
<td colspan="5">
<span class="gap"></span>
<span class="dealtime" title="2016-10-08 07:04:12">2016-10-08 07:04:12</span>
<input id="datasubmit-37327761306" value="2016-10-08 07:04:12" type="hidden">

</span>
<a href="#none" clstag="click|keycount|orderlist|dingdanshanchu" class="order-del" _orderid="37327761306" _passkey="10413CA642EDECE687F5F7A4F38AFB6E" style="display: none;" title="删除"></a>

</div>
</td>

 如果想要获取table里面的html信息该如何操作呢?

selenium中有个page_source属性,但是那个是获取整个网页的html而不是元素的html

driver.find_element_by_id('tb-37327761306').get_attribute('innerHTML')

通过 get_attribute('innerHTML')的方式可以获取某个元素的html信息
