无法使用python beautifulsoup从Web抓取中找到HTML中的表格标签，以及如何抓取具有多个页面的表格

我有2个独立的问题：

问题1

I'm trying to scrape some tables from this website. See the attached image below.

因此，我编写了这段代码，直到这里：

from bs4 import BeautifulSoup
import requests


url = 'https://transparencia.registrocivil.org.br/registros'

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36'}

source = requests.get(url, headers=headers).text

soup = BeautifulSoup(source, 'html.parser')

table = soup.find('table')

print(table.prettify())

This code isn't working and the table returned is NoneType. It seems that BeautifulSoup can't find it. What am I doing wrong to scrape the table?

完成此操作后，我将解释问题的第二部分：

问题2

My main idea is to scrape data using the selectors from the image, referring each year, month, region, state to scrape city-data.

这些表中的一些很大，分布在页面中，如您在网站中某些表的末尾所见。如何运行所有这些页面以获取每年，每月，地区和州的所有数据？
