三、按列添加
importprettytableaspt#按行添加数据tb=pt.PrettyTable()tb.field_names=['name','age','height','weight']tb.add_row(['autofelix',25,174,65])tb.add_row(['大神',23,164,55])tb.add_row(['飞兔小哥',27,184,69.5])#按列添加数据tb.add_column('sex',['男','女','男'])print(tb)#+-----------+-----+--------+--------+-----+#|name|age|height|weight|sex|#+-----------+-----+--------+--------+-----+#|autofelix|25|174|65|男|#|大神|23|164|55|女|#|飞兔小哥|27|184|69.5|男|#+-----------+-----+--------+--------+-----+
四、输出风格
importprettytableaspt#按行添加数据tb=pt.PrettyTable()tb.field_names=['name','age','height','weight']tb.add_row(['autofelix',25,174,65])tb.add_row(['大神',23,164,55])tb.add_row(['飞兔小哥',27,184,69.5])#风格tb.set_style(pt.MSWORD_FRIENDLY)print(tb)#|name|age|height|weight|#|autofelix|25|174|65|#|大神|23|164|55|#|飞兔小哥|27|184|69.5|
五、获取字符串
importprettytableaspt#按行添加数据tb=pt.PrettyTable()tb.field_names=['name','age','height','weight']tb.add_row(['autofelix',25,174,65])tb.add_row(['大神',23,164,55])tb.add_row(['飞兔小哥',27,184,69.5])#不打印，获取表格字符串s1=tb.get_string()print(s1)#+-----------+-----+--------+--------+#|name|age|height|weight|#+-----------+-----+--------+--------+#|autofelix|25|174|65|#|大神|23|164|55|#|飞兔小哥|27|184|69.5|#+-----------+-----+--------+--------+#或者可以只获取指定列或行s2=tb.get_string(fields=['name','age'],start=1,end=4)print(s2)#+----------+-----+#|name|age|#+----------+-----+#|大神|23|#|飞兔小哥|27|#+----------+-----+
六、表格样式设置
importprettytableaspt#按行添加数据tb=pt.PrettyTable()tb.field_names=['name','age','height','weight']tb.add_row(['autofelix',25,174,65])tb.add_row(['大神',23,164,55])tb.add_row(['飞兔小哥',27,184,69.5])#设定左对齐tb.align='l'#设定数字输出格式tb.float_format='2.2'#设定边框连接符为'*"tb.junction_char='*'#设定排序方式tb.sortby='age'#设定左侧不填充空白字符tb.left_padding_width=0#不显示边框#tb.border=0#修改边框分隔符tb.horizontal_char='+'print(tb)#*++++++++++*++++*+++++++*+++++++*#|name|age|height|weight|#*++++++++++*++++*+++++++*+++++++*#|大神|23|164|55|#|autofelix|25|174|65|#|飞兔小哥|27|184|69.50|#*++++++++++*++++*+++++++*+++++++*
七、输出成HTML
importprettytableaspt#按行添加数据tb=pt.PrettyTable()tb.field_names=['name','age','height','weight']tb.add_row(['autofelix',25,174,65])tb.add_row(['大神',23,164,55])tb.add_row(['飞兔小哥',27,184,69.5])#输出HTML代码s=tb.get_html_string()print(s)#<table>#<thead>#<tr>#<th>name</th>#<th>age</th>#<th>height</th>#<th>weight</th>#</tr>#</thead>#<tbody>#<tr>#<td>autofelix</td>#<td>25</td>#<td>174</td>#<td>65</td>#</tr>#<tr>#<td>大神</td>#<td>23</td>#<td>164</td>#<td>55</td>#</tr>#<tr>#<td>飞兔小哥</td>#<td>27</td>#<td>184</td>#<td>69.5</td>#</tr>#</tbody>#</table>
八、复制
importprettytableaspt#按行添加数据tb=pt.PrettyTable()tb.field_names=['name','age','height','weight']tb.add_row(['autofelix',25,174,65])tb.add_row(['大神',23,164,55])tb.add_row(['飞兔小哥',27,184,69.5])tb.horizontal_char='.'tb2=tb.copy()tb.align='l'tb2.align='r'print(tb)print(tb2)#+...........+.....+........+........+#|name|age|height|weight|#+...........+.....+........+........+#|autofelix|25|174|65|#|大神|23|164|55|#|飞兔小哥|27|184|69.5|#+...........+.....+........+........+#+...........+.....+........+........+#|name|age|height|weight|#+...........+.....+........+........+#|autofelix|25|174|65|#|大神|23|164|55|#|飞兔小哥|27|184|69.5|#+...........+.....+........+........+
