AttributeError - 网页抓取 - Python - Selenium

我需要从网上抓取下表，但我无法用“find_all”函数解决这个问题。PyCharm 总是说：

AttributeError: 'NoneType' object has no attribute 'find_all'

我不知道出了什么问题。尝试使用 table.find_all("tr") 或 table.find_all('tr') 字符和下一个属性，如 table.find_all("tr", attrs={"class": "table table-export"}) 和下一个选项，没有任何效果。请你能告诉我我做错了什么吗？

桌子：

<div class="table-options">
    <table class="table table-export">
                <thead>
                <tr>
                    <!-- ngIf: ActuallyPoints && ActuallyPoints.name == 'AXB' --><th ng-if="currentRole &amp;&amp; currentRole.name == 'AXB'" class="id check">
                        <label ng-click="selectAll()"><input disabled="" id="select-all" type="checkbox" ng-model="all" class="valid value-ng">All</label>
                    </th><!-- end ngIf: currentRole && currentRole.name == 'AXB' -->
                    <th>AAA</th>
                    <th>BBB</th>
                    <th>CCC</th>
        </tr>
                </thead>
                <tbody>
<!-- ngRepeat: x in ErrorStatus --><tr ng-repeat="x in ErrorStatus" class="random-id">
                    <!-- ngIf: currentRole && currentRole.name == 'AXB' --><td ng-if="currentRole &amp;&amp; currentRole.name == 'AXB'" class="random-id">
                        <input type="checkbox" ng-model="x.checked" ng-change="selectOne(x)" class="valid value-ng">
                    </td><!-- end ngIf: currentRole && currentRole.name == 'AXB' -->
                    <td class="pax">111</td>
                    <td class="pax">222</td>
                    <td class="pax">333</td>
                    </td>
                </tr><!-- end ngRepeat: x in ErrorStatus -->
                </tbody>
            </table>
        </div>

代码：

import lxml
from urllib.request import urlopen
from bs4 import BeautifulSoup

url = 'xxx'
website = request.urlopen(url).read()

soup = BeautifulSoup(website, "lxml")

table = soup.find("table", attrs={"class": "table table-export"})
rows = table.find_all('tr')

非常感谢。
