我有這個網頁：http://waterdata.usgs.gov/nwis/wys_rpt?dd_parm_cds=002_00060&wys_water_yr=2015&site_no=06935965美麗的湯不會從HTML對象返回全表
，我是希望能颳去這樣的信息：
的信息存儲在這裏一個表，顯示標題後的第一個兩行展開：
因此，我設置並學習了一個BeautifulSoup，並找到我的表格（這是頁面上的最後一個，因此是tables[-1]），但它不會拾取整個表格 - 在「年度總計」行名稱/條目之後停止。
代碼：
from bs4 import BeautifulSoup
import requests
base_url = 'http://waterdata.usgs.gov/nwis/wys_rpt?dd_parm_cds=002_00060&wys_water_yr=2015&site_no='
site = '06935965'
url = base_url + site
r = requests.get(url)
soup = BeautifulSoup(r.text,'html.parser')
tables = soup.find_all('table')
table = tables[-1]
print(table.text)
輸出：
SUMMARY STATISTICS
Water Year 2015
Water Years 2000 - 2015
Annual total
而這一切！整個表被拾取的請求調用：

有人能看到爲什麼美麗的湯被省略了表的其餘部分？
