我如何从这个链接的网页刮去子标题？

我做了一个网站刮板从看起来像这样的网页刮数据（它刮掉表）：https://www.techpowerup.com/gpudb/2/我如何从这个链接的网页刮去子标题？

的问题是，我的程序，由于某种原因，只刮值，而不是副标题。例如（点击链接），它只会删除“R420”，“130nm”，“160万”等，但不包括“GPU名称”，“工艺尺寸”，“晶体管”等。

我要添加哪些代码才能获取副标题？这是我的代码：

import csv 
import requests 
import bs4 
url = "https://www.techpowerup.com/gpudb/2" 


#obtain HTML and parse through it 
response = requests.get(url) 
html = response.content 
import sys 
reload(sys) 
sys.setdefaultencoding('utf-8') 
soup = bs4.BeautifulSoup(html, "lxml") 
tables = soup.findAll("table") 

#reading every value in every row in each table and making a matrix 
tableMatrix = [] 
for table in tables: 
    list_of_rows = [] 
    for row in table.findAll('tr'): 
     list_of_cells = [] 
     for cell in row.findAll('td'): 
      text = cell.text.replace('&nbsp;', '') 
      list_of_cells.append(text) 
     list_of_rows.append(list_of_cells) 
    tableMatrix.append((list_of_rows, list_of_cells)) 

#(YOU CAN PROBABLY IGNORE THIS)placeHolder used to avoid duplicate data from appearing in list 
placeHolder = 0 
excelTable = [] 
for table in tableMatrix: 
    for row in table: 
     if placeHolder == 0: 
      for entry in row: 
       excelTable.append(entry) 
      placeHolder = 1 
     else: 
      placeHolder = 0 
    excelTable.append('\n') 

for value in excelTable: 
    print value 
    print '\n' 


#create excel file and write the values into a csv 
fl = open(str(count) + '.csv', 'w') 
writer = csv.writer(fl) 
for values in excelTable: 
    writer.writerow(values) 
fl.close()
