我正在尝试从以下网站提取数据并导出到excel。我试图提取数据，但我得到的比我想要的更多，我无法保存到excel数据。
import requests
from BeautifulSoup import BeautifulSoup
url_libor = 'http://online.wsj.com/mdc/public/page/2_3020-libor.html'
response_libor = requests.get(url_libor)
html_libor = response_libor.content
soup1_libor = BeautifulSoup(html_libor)
table_libor = soup1_libor.find('table', attrs={'style': 'border-top:0px solid #CCCCCC;border-bottom:0px;'})
table_libor1 = soup1_libor.find('div', attrs={'class': 'tableDesc'})
table_libor1.append(table_libor)
print table_libor1.prettify()
获取HTML格式，但我想以表格格式。表的第一部分
