tabulate函数官方文档
tabulate直译是制表，让python实现表格化显示。
tabulate.tabulate(tabular_data, headers=(), tablefmt=u'simple', floatfmt=u'g', numalign=u'decimal', stralign=u'left', missingval=u'')
tabular_data:需要显示的内容。
headers：表头
tablefmt：显示格式，共有如下各种：
- "plain"
- "simple"
- "github"
- "grid"
- "fancy_grid"
- "pipe"
- "orgtbl"
- "jira"
- "presto"
- "psql"
- "rst"
- "mediawiki"
- "moinmoin"
- "youtrack"
- "html"
- "latex"
- "latex_raw"
- "latex_booktabs"
- "textile"
常用函数
tabulate是一个模块，其中包括tabulate.tabulate()函数
from tabulate import tabulate
tabulate.PRESERVE_WHITESPACE = True # 保留空格
中文对齐||wcwidth模块
tabulate默认没有考虑中文字符宽度，因此无法对齐，如要实现对齐，需要wcwidth 包。
输出表格样式
tabulate 提供多种表格输出风格，示例如下：
plain
>>> print(tabulate(table_data, headers=table_header, tablefmt='plain'))

Tom 90 80 85Jim 70 90 80Lucy 90 70 90注意到， tabulate 函数也可以用来生成 html 表格定义代码。 此外，还支持 mediawiki、 moinmoin 、 youtrack 、 latex 、 latex_raw 、 latex__booktabs 、 textile 表格生成。
