使用pip即可十分方便的安装PrettyTable，如下：
pip install PrettyTable
github上有PrettyTable的使用说明，链接如下：https://github.com/dprince/python-prettytable
以下是具体的使用示例：
import prettytable as pt## 按行添加数据tb = pt.PrettyTable() tb.field_names = ["City name", "Area", "Population", "Annual Rainfall"] tb.add_row(["Adelaide",1295, 1158259, 600.5]) tb.add_row(["Brisbane",5905, 1857594, 1146.4]) tb.add_row(["Darwin", 112, 120900, 1714.7]) tb.add_row(["Hobart", 1357, 205556,619.5])print(tb)
+-----------+------+------------+-----------------+ | City name | Area | Population | Annual Rainfall | +-----------+------+------------+-----------------+ | Adelaide | 1295 | 1158259 | 600.5 | | Brisbane | 5905 | 1857594 | 1146.4 | | Darwin | 112 | 120900 | 1714.7 | | Hobart | 1357 | 205556 | 619.5 | +-----------+------+------------+-----------------+
## 按列添加数据tb.add_column('index',[1,2,3,4])print(tb)+-----------+------+------------+-----------------+-------+ | City name | Area | Population | Annual Rainfall | index | +-----------+------+------------+-----------------+-------+ | Adelaide | 1295 | 1158259 | 600.5 | 1 | | Brisbane | 5905 | 1857594 | 1146.4 | 2 | | Darwin | 112 | 120900 | 1714.7 | 3 | | Hobart | 1357 | 205556 | 619.5 | 4 | +-----------+------+------------+-----------------+-------+
## 使用不同的输出风格tb.set_style(pt.MSWORD_FRIENDLY)print('--- style：MSWORD_FRIENDLY -----')print(tb) tb.set_style(pt.PLAIN_COLUMNS)print('--- style：PLAIN_COLUMNS -----')print(tb)## 随机风格，每次不同tb.set_style(pt.RANDOM)print('--- style：MSWORD_FRIENDLY -----')print(tb) tb.set_style(pt.DEFAULT)print('--- style：DEFAULT -----')print(tb)

## 不打印，获取表格字符串s = tb.get_string()print(s)## 可以只获取指定列或行s = tb.get_string(fields=["City name", "Population"],start=1,end=4)print(s)
+-----------+------+------------+-----------------+ | City name | Area | Population | Annual Rainfall | +-----------+------+------------+-----------------+ | Adelaide | 1295 | 1158259 | 600.5 | | Brisbane | 5905 | 1857594 | 1146.4 | | Darwin | 112 | 120900 | 1714.7 | | Hobart | 1357 | 205556 | 619.5 | +-----------+------+------------+-----------------+ +-----------+------------+ | City name | Population | +-----------+------------+ | Brisbane | 1857594 | | Darwin | 120900 | | Hobart | 205556 | +-----------+------------+
## 自定义表格输出样式### 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 = "City name"### 设定左侧不填充空白字符tb.left_padding_width = 0print(tb)
*----------*-----*-----------*----------------* |City name |Area |Population |Annual Rainfall | *----------*-----*-----------*----------------* |Adelaide |1295 |1158259 |600.50 | |Brisbane |5905 |1857594 |1146.40 | |Darwin |112 |120900 |1714.70 | |Hobart |1357 |205556 |619.50 | *----------*-----*-----------*----------------*
## 不显示边框tb.border = 0print(tb)## 修改边框分隔符tb.set_style(pt.DEFAULT) tb.horizontal_char = '+'print(tb)

## prettytable也支持输出HTML代码s = tb.get_html_string()print(s)
<table> <tr> <th>City name</th> <th>Area</th> <th>Population</th> <th>Annual Rainfall</th> </tr> <tr> <td>Adelaide</td> <td>1295</td> <td>1158259</td> <td>600.50</td> </tr> <tr> <td>Brisbane</td> <td>5905</td> <td>1857594</td> <td>1146.40</td> </tr> <tr> <td>Darwin</td> <td>112</td> <td>120900</td> <td>1714.70</td> </tr> <tr> <td>Hobart</td> <td>1357</td> <td>205556</td> <td>619.50</td> </tr> </table>
## 使用copy方法复制对象#tb.set_style(pt.DEFAULT)tb.horizontal_char = '.'tb2 = tb.copy() tb.align = 'l'tb2.align = 'r'print(tb)print(tb2)## 直接赋值，得到的是索引tb.horizontal_char = '-'tb.aliign = 'l'tb3 = tb tb3.align = 'r'print(tb)print(tb3)
