PrettyTable安装

使用pip即可十分方便的安装PrettyTable，如下：

pip install PrettyTable

PrettyTable使用示例

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)

## 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 |

|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>

 <th>Area</th>
 <th>Population</th>
 <th>Annual Rainfall</th>

## 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)
