3.使用实例http://www.cndba.cn/Expect-le/article/391

>>> from prettytable import PrettyTable
>>> x = PrettyTable(["City name", "Area", "Population", "Annual Rainfall"])
>>> x.align["City name"] = "l"# Left align city names
>>> x.padding_width = 1# One space between column edges and contents (default)
>>> x.add_row(["Adelaide",1295, 1158259, 600.5])  
>>> x.add_row(["Brisbane",5905, 1857594, 1146.4]) 
>>> x.add_row(["Darwin", 112, 120900, 1714.7])
>>> x.add_row(["Hobart", 1357, 205556, 619.5])
>>> x.add_row(["Sydney", 2058, 4336374, 1214.8])
>>> x.add_row(["Expect-le", 1566, 3806092, 646.9])

结果：非常好看

>>> print x
