python2 爬虫爬取表格写入csv换行

我在试着爬取CNKI的这个表格的部分字段，然后这个表格的作者列中，有些是含有多个名字，所以就是多条标签。然后我抓取下来的名称和作者就对不上，多个作者的标签会换行，那么我应该如何做才能写入csv时完成这种一条文献对应多个作者名字。

Python2

# coding:utf-8
import re
import csv
import codecs
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
import warnings
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

warnings.filterwarnings("ignore")
driver=webdriver.Firefox()
driver.get("http://epub.cnki.net/kns/brief/result.aspx?dbprefix=scdb&action=scdbsearch&db_opt=SCDB")
driver.find_element_by_link_text(u'专业检索').click()
time.sleep(3)

driver.find_element_by_css_selector("textarea[id=\"expertvalue\"]").clear()
driver.find_element_by_css_selector("textarea[id=\"expertvalue\"]").send_keys(u"TI='生态'")
driver.find_element_by_id("btnSearch").click()
driver.switch_to_frame("iframeResult")

page=driver.page_source
note=BeautifulSoup(page)
f = open('tabletable.csv', 'wb')
f.write(codecs.BOM_UTF8)
urlitems=note.findAll(name="a", attrs={"class":"fz14"})
nameitems=note.findAll(name="a", attrs={"target":"knet"})
textitems=note.findAll(name="a", attrs={"class":"KnowledgeNetLink","target":"_blank"})

header=['url','name','writer','choose']
writer = csv.writer(f,delimiter=',')
writer.writerow(header)
csvrow1=[]
csvrow2=[]
csvrow3=[]
csvrow4=[]
for urlinks in urlitems:
    csvrow1.append('http://www.cnki.net' + urlinks.get('href'))

for names in urlitems:
    csvrow2.append(names.get_text())


for writers in nameitems:
    csvrow3.append(writers.get_text())

for chooses in textitems:
    csvrow4.append(chooses.get_text())

for i in zip(csvrow1, csvrow2, csvrow3, csvrow4):
    f.write(i[0] + ',' + i[1] + ',' + i[2] + ',' + i[3] + '\n')
f.close()
