format函数运行错误？

import requests
from bs4 import BeautifulSoup
import bs4

 def getHtmlText(url):
        try:
            r = requests.get(url, timeout = 30)
            r.raise_for_status()
            r.encoding = r.apparent_encoding
            return r.text
        except:
            print('Error')
            return ""

 def fillUnivlist(ulist, html):
    soup = BeautifulSoup(html, 'html.parser')
    for tr in soup.find('tbody').children:
        if isinstance(tr, bs4.element.Tag):
        #筛选出属性为Tag的tr，去掉其他文本
            tds = tr('td')
            ulist.append([tds[0].string,tds[1].string,
            tds[2].string,tds[3].string])

 def printUnivlist(ulist, num):
        space = "{0:^10}\t{1:^10}\t{2:^10}\t{3:^6}"
        print(space.format("排名","学校名称","地区","总分",
        chr(12288)))
        for i in range(num):
            u = ulist[i]
            print(space.format(u[0],u[1],u[2],u[3],
            chr(12288)))

 def main():
        uinfo =[]
        url = 'http://www.zuihaodaxue.com/zuihaodaxuepaiming2016.html'
        html = getHtmlText(url)
        fillUnivlist(uinfo, html)
        printUnivlist(uinfo, 20)#打印20所学校的排名
main()

第三列开始就无法对齐了，求大神指导
