无法将表格导入熊猫

Question

我正在尝试将网站中的信息导入熊猫数据框，但无法正常工作。有人可以告诉我我做错了什么吗？这是我的代码：

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline
import requests

header = {
  "User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36",
  "X-Requested-With": "XMLHttpRequest"
}

url = 'https://new.cryptoxscanner.com/binance/live'
r = requests.get(url, headers=header)
dfs = pd.read_html(r.text)
