问题：
使用python获取表标记数据的特定部分
高德水
我在本地驱动器中保存了一个html，它由多个表组成，但我想从整个页面中提取一些特定表并导出到CSV。所以我用python写了一个小脚本，它给了我完整的html文本数据，现在我不知道如何从这些数据中提取数据。
Python代码-
import pandas as pd
url = "table1.html"
tables = pd.read_html(url)[0]
print(tables)
html文件是-
null
<!--?xml version="1.0" encoding="utf-16"?-->
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse;" width="100%">

由于上面所需的数据在html文件中多次出现，所以我想在html文件中得到这些列中出现的所有多个数据。由于html文件有点复杂，而且我是新手，我不知道如何开始。谢谢你的帮助
