python - 在python单个表格单元格中添加多行

Question

我不确定如何绘制如下所示的表格，我尝试使用漂亮的表格但无法在一个单元格中放置多行。

注意:行数应该基于字符串的数量，所以我想每行放一些 n 个字符串。

有人可以帮忙吗？

+---- +-------------------+-------------------------------------------------------+
| Id  | Name              | Comment                                               |
+-----+-------------------+-------------------------------------------------------+
| 1   |  Alvina Skiles    | Dolor qui rerum est sed. Sed ipsa repudiandae et      |
|     |                   | Non explicabo voluptas impedit rerum dignissimos.     |
|     |                   | Minima voluptatibus sint voluptates similique.'       |
+-----+-------------------+-------------------------------------------------------+
| 2   |  Chasity Lakin    | Nesciunt ea voluptatem rerum eos rerum ut soluta      |
|     |                   | Animi totam rerum fugiat consectetur odio et          |
|     |                   | repellendus                                           |

这是我构建表的数据结构:

[
    {
        "id": "1",
        "name": "Alvina Skiles",
        "comment": 'Dolor qui rerum est sed. Sed ipsa repudiandae et. Non explicabo voluptas impedit rerum dignissimos. Minima voluptatibus
    },
    {
        "id": "2",
        "name" : 'Chasity Lakin',
        "comment": 'Nesciunt ea voluptatem rerum eos rerum ut soluta. Animi totam rerum fugiat consectetur odio et repellendus.',
    },
    {
        "id": "3",
        "name" : 'Miss Brennan Kiehn',
        "comment": 'Nulla placeat saepe voluptatem molestias dolores ex. Reiciendis nostrum adipisci qui enim explicabo.
    },
]

看起来prettytable 可以很好地处理换行符，因此快速格式化功能可能就可以解决问题。这是我的示例:

import prettytable
from prettytable import ALL as ALL
items_table = prettytable.PrettyTable(hrules=ALL)
items_table.field_names = ["id", "name", "comment"]

items = [
    {
        "id": "1",
        "name": "Alvina Skiles",
        "comment": 'Dolor qui rerum est sed. Sed ipsa repudiandae et. Non explicabo voluptas impedit rerum dignissimos. Minima voluptatibus'
    },
    {
        "id": "2",
        "name" : 'Chasity Lakin',
        "comment": 'Nesciunt ea voluptatem rerum eos rerum ut soluta. Animi totam rerum fugiat consectetur odio et repellendus.'
    },
    {
        "id": "3",
        "name" : 'Miss Brennan Kiehn',
        "comment": 'Nulla placeat saepe voluptatem molestias dolores ex. Reiciendis nostrum adipisci qui enim explicabo.'
    },
]

def format_comment(comment, max_line_length):
    #accumulated line length
    ACC_length = 0
    words = comment.split(" ")
    formatted_comment = ""
    for word in words:
        #if ACC_length + len(word) and a space is <= max_line_length 
        if ACC_length + (len(word) + 1) <= max_line_length:
            #append the word and a space
            formatted_comment = formatted_comment + word + " "
            #length = length + length of word + length of space
            ACC_length = ACC_length + len(word) + 1
        else:
            #append a line break, then the word and a space
            formatted_comment = formatted_comment + "\n" + word + " "
            #reset counter of length to the length of a word and a space
            ACC_length = len(word) + 1
    return formatted_comment

for item in items:
    item["comment"] = format_comment(item["comment"], 42)
    items_table.add_row([item["id"], item["name"], item["comment"]])

print(items_table)

这是输出:
