生成markdown表的泛型函数.

from __future__ import annotations

def build_row(field_widths: dict[str, int], row: dict[str, str]) -> str:
    pipe_escape = '\|'
    inner = '|'.join(f'{row[header].replace("|", pipe_escape).ljust(width)}' for header, width in field_widths.items())
    return f'|{inner}|'

def make_table(headers: list[str], rows: list[dict[str, str]]) -> str:
    field_widths = {}
    for header in headers:
        field_widths[header] = len(header) + header.count('|')

    for row in rows:
        for field_name, value in row.items():
            if field_name not in headers:
                raise ValueError(f"field name {field_name!r} not in headers")
            current_width = field_widths[field_name]
            this_width = len(value) + value.count('|')
            if this_width > current_width:
                field_widths[field_name] = this_width

    header_sep = build_row(field_widths, {h: '-' * field_widths[h] for h in headers})
    header_row = {h:h for h in headers}
    header = build_row(field_widths, header_row)
    table_rows = [build_row(field_widths, row) for row in rows]
    newline = '\n'
    table = f'{header}\n{header_sep}\n{newline.join(table_rows)}'
    return table

然后你可以使用这个函数来创建一个你想要的带有你特定的标题和数据的表：

field_names = ['File changed', 'Summary']
rows = [
    {'File changed': '/path/to/foo/bar/baz', 'Summary': '-100 +200'},
    {'File changed': '/path/to/bacon/eggs/spam', 'Summary': '-1 +2'},
    {'File changed': '/path/to/buzz/crash/split', 'Summary': '-1234 +1234'},
]

print(make_table(headers=field_names, rows=rows))

将输出：

|File changed             |Summary    |
|-------------------------|-----------|
|/path/to/foo/bar/baz     |-100 +200  |
|/path/to/bacon/eggs/spam |-1 +2      |
|/path/to/buzz/crash/split|-1234 +1234|

在GitHub markdown中查看时，看起来像：

当将正文发送到GitHub API时，您需要确保其格式正确。也就是说：请求的主体需要进行JSON编码。如果你使用requests库，当你使用json关键字传递comment_data时，这会为你完成，例如。requests.post(comment_url, json=comment_data)，否则您需要正确编码您的有效负载。
