您可以使用texttable与周围的小黑客：

import texttable

table = texttable.Texttable()
table.add_rows([['Projects', 'Number'],
                ['Project A\nProject B\nProject C\nProject D', '5\n9\n8\n2'],
                ['Total', 24]])
print(table.draw())

输出量：

+-----------+--------+
| Projects  | Number |
+===========+========+
| Project A | 5      |
| Project B | 9      |
| Project C | 8      |
| Project D | 2      |
+-----------+--------+
| Total     | 24     |
+-----------+--------+

漂亮的表中没有单独的创建页脚的函数。不过你可以做一些小技巧来创建，如果你是特别使用只漂亮的表如下

sum = 0
for row in outTbl:
     sum = sum + int(row.get_string(fields=["Number"]).split('\n')[3].replace('|','').replace(' ',''))
outTbl.add_row(['------------','-----------'])
outTbl.add_row(['Total',sum])
print (outTbl)

或者，如果您正在寻找带有页脚的特定函数，您可以查看https://stackoverflow.com/a/26937531/3249782，了解可以使用的不同方法

我今天遇到了同样的问题，并使用了以下方法将表的最后n行作为结果行，由一条水平线分隔（就像分隔标题的一条线）：

from prettytable import PrettyTable

t = PrettyTable(['Project', 'Numbers'])
t.add_row(['Project A', '5'])
t.add_row(['Project B', '9'])
t.add_row(['Project C', '8'])
t.add_row(['Project D', '2'])

# NOTE: t is the prettytable table object
# Get string to be printed and create list of elements separated by \n
list_of_table_lines = t.get_string().split('\n')

# Use the first line (+---+-- ...) as horizontal rule to insert later
horizontal_line = list_of_table_lines[0]

# Print the table
# Treat the last n lines as "result lines" that are seperated from the
# rest of the table by the horizontal line
result_lines = 1
print("\n".join(list_of_table_lines[:-(result_lines + 1)]))
print(horizontal_line)
print("\n".join(list_of_table_lines[-(result_lines + 1):]))

这将产生以下输出：

+-----------+---------+
|  Project  | Numbers |
+-----------+---------+
| Project A |    5    |
| Project B |    9    |
| Project C |    8    |
+-----------+---------+
| Project D |    2    |
+-----------+---------+

我知道我迟到了，但是我创建了一个函数来自动向表中添加一个“总计”行。现在还不能解决列是否比表宽的问题。
Python 3.6 ++
功能说明：

def table_footer(tbl, text, dc):
    res = f"{tbl._vertical_char} {text}{' ' * (tbl._widths[0] - len(text))} {tbl._vertical_char}"

    for idx, item in enumerate(tbl.field_names):
        if idx == 0:
            continue
        if not item in dc.keys():
            res += f"{' ' * (tbl._widths[idx] + 1)} {tbl._vertical_char}"
        else:
            res += f"{' ' * (tbl._widths[idx] - len(str(dc[item])))} {dc[item]} {tbl._vertical_char}"

    res += f"\n{tbl._hrule}"
    return res

使用方法：

tbl = PrettyTable()
tbl.field_names = ["Symbol", "Product", "Size", "Price", "Subtotal", "Allocation"]
tbl.add_row([......])

print(tbl)
print(table_footer(tbl, "Total", {'Subtotal': 50000, 'Allocation': '29 %'}

+--------+-------------------------------+-------+---------+----------+------------+
| Symbol |            Product            |  Size |  Price  | Subtotal | Allocation |
+--------+-------------------------------+-------+---------+----------+------------+
|    AMD |   Advanced Micro Devices Inc  | 999.9 |  75.99  |  20000.0 |      23.00 |
|   NVDA |          NVIDIA Corp          |  88.8 |  570.63 |  30000.0 |       6.00 |
+--------+-------------------------------+-------+---------+----------+------------+
| Total  |                               |       |         |    50000 |       29 % |
+--------+-------------------------------+-------+---------+----------+------------+

在检查了pretty table的源代码后，你可以看到，在打印表格后，你可以得到每个列的宽度。使用这个你可以自己创建一个页脚，因为漂亮的表不给予你这个选项。以下是我的方法：

from prettytable import PrettyTable

t = PrettyTable(['Project', 'Numbers'])
t.add_row(['Project A', '5'])
t.add_row(['Project B', '9'])
t.add_row(['Project C', '8'])
t.add_row(['Project D', '2'])
print(t)
total = '24'
padding_bw = (3 * (len(t.field_names)-1))
tb_width = sum(t._widths)
print('| ' + 'Total' + (' ' * (tb_width - len('Total' + total)) +
                        ' ' * padding_bw) + total + ' |')
print('+-' + '-' * tb_width + '-' * padding_bw + '-+')

下面是输出：

+-----------+---------+
|  Project  | Numbers |
+-----------+---------+
| Project A |    5    |
| Project B |    9    |
| Project C |    8    |
| Project D |    2    |
+-----------+---------+
| Total            24 |
+---------------------+

只需更改代码中的总var，一切都应该正常工作

我偷了@Niels的解决方案，并在最后num_footers行之前使用一个打印机打印：

def print_with_footer(ptable, num_footers=1):
    """ Print a prettytable with an extra delimiter before the last `num` rows """
    lines = ptable.get_string().split("\n")
    hrule = lines[0]
    lines.insert(-(num_footers + 1), hrule)
    print("\n".join(lines))

prettytable通过将divider=True传递给add_row()来支持页脚。
下面是一个来自https://pypi.org/project/prettytable/的示例
验证码：

x = PrettyTable()
x.field_names = ["City name", "Area", "Population", "Annual Rainfall"]
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], divider=True)
x.add_row(["Melbourne", 1566, 3806092, 646.9])
x.add_row(["Perth", 5386, 1554769, 869.4])
x.add_row(["Sydney", 2058, 4336374, 1214.8])
