python 爬虫 re 如何抓取 这种html的表格代码？代码基本都是一样的，但是试了好久就是没办法
试着抓取了下，
pattern = re.compile('采购单(.*?)</b>.*?<tr>.*?height.*?center(.*?)</div>.*?height=(str).*?center(.*?)</div>', re.S)
结果都是把供应商这行表头抓取了，下面的内容却不抓取。
也尝试过用bs4，也是搞不定。
请教高手，正则该如何写？

正则表达式
text = 你的文本
t = re.findall("align='center'\s*>(.*?)<",text,re.S)
for i in t:
print i
