我正在使用django beautifulsoup来获取html表格中的所有数据。我有代码剥离表并将表数据保存为列表列表：
soup = bs.BeautifulSoup(html_source, 'lxml')
table = soup.find('table', {'id': 'detail'})
rows = table.findAll('tr')
data = [[td.findChildren(text=True) for td in tr.findAll(['th', 'td'])] for tr in rows]
data = [[u"".join(d).strip() for d in l] for l in data]
此代码到目前为止运行良好，但不知何故它不会捕获此html表的整个数据。它只获得thead行。我无法弄清楚为什么？

修改
我打印了soup个对象并浏览了所有html代码，令人惊讶的是它只包含表格的thead而不是tbody，这是一个错误boutifulsoup？这是beautifulsoup4捕获的表的唯一部分：
<table class="table_type1" data-tdborder="" id="detail">
<colgroup>
<col width="38"/>
<col/>
<col/>
<col width="140"/>
</colgroup>
<thead>
<tr>
<th>No.</th>
<th>Status</th>
<th>Location</th>
<th>Event Date</th>
</tr>
</thead>
