+------------+-------------+-----------------------+------------------+-------------------+---------------+------------------------------+--------+
| Technology | All Backlog | All Backlog Completed | Percent Complete | Backlog Remaining | Internal ONLY | Ext/Int & Ready For External | Non-IC |
+------------+-------------+-----------------------+------------------+-------------------+---------------+------------------------------+--------+
| Tech 1 | 2395 | 1069 | 44.63% | 1326 | 34 | 219 | 822 |
+------------+-------------+-----------------------+------------------+-------------------+---------------+------------------------------+--------+
假设这个表是一个 DataFrame ...（索引被删除）
右 4 列是 INT。我希望它们也显示完成百分比，就像我在其他列中一样，这些列被格式化为显示 %。比如……
+------------+-------------+-----------------------+------------------+-------------------+---------------+------------------------------+--------------+
| Technology | All Backlog | All Backlog Completed | Percent Complete | Backlog Remaining | Internal ONLY | Ext/Int & Ready For External | Non-IC |
+------------+-------------+-----------------------+------------------+-------------------+---------------+------------------------------+--------------+
| Tech 1 | 2395 | 1069 | 44.63% | 1326 | 34 (3.18%) | 219 (20.48%) | 822 (76.89%) |
+------------+-------------+-----------------------+------------------+-------------------+---------------+------------------------------+--------------+
我查看了 map、applymap 和其他...但我能得到的唯一接近的是：
+------------+-------------+-----------------------+------------------+-------------------+--------------------------------------+-----------------------------------------+----------------------------------------+
| Technology | All Backlog | All Backlog Completed | Percent Complete | Backlog Remaining | Internal ONLY | Ext/Int & Ready For External | Non-IC |
+------------+-------------+-----------------------+------------------+-------------------+--------------------------------------+-----------------------------------------+----------------------------------------+
| Tech 1 | 2395 | 1069 | 44.63% | 1326 | 34 (0 3.18% 1 3.18% dtype: float64%) | 219 (0 20.49% 1 20.49% dtype: float64%) | 822(0 76.89% 1 76.89% dtype: float64%) |
+------------+-------------+-----------------------+------------------+-------------------+--------------------------------------+-----------------------------------------+----------------------------------------+
我认识到它显示得很奇怪，因为它试图将一个系列而不是相应的数据附加到单元格中......因此我想要映射，但我发现没有任何东西似乎符合需要。
这是我目前正在使用的代码。
def get_IC_percomp(df:pd.DataFrame):
"""

logger.debug('Starting get_IC_percomp()...')
column_list = ['Internal ONLY', 'Ext/Int & Ready For External', 'Non-IC']
new_dict = {column: None for column in column_list} # could also do: dict.fromkeys(keys, None)
for col in column_list:
#if float(df['All Backlog Completed'].applymap(float)) == 0.0:
# new_dict[col] = 0
#else:
# new_dict[col] = df[col] / df['All Backlog Completed']
new_dict[col] = df[col] / df['All Backlog Completed'] * 100
logger.debug('Ending get_IC_percomp()...')
return new_dict
def chg_font_fmt(data_dict:dict):

new_dict = dict()
new_dict['Percent Complete'] = '{:.2f}%'
new_dict['Total Percent Complete'] = '{:.2f}%'

if data_dict is not None:
new_dict['Internal ONLY'] = '{:}' + ' ({}%)'.format(data_dict['Internal ONLY'])

可能在这里找到了答案：stackoverflow.com/a/54026256/10474024 但是测试一直没有结果。
【问题讨论】：
-
花点时间阅读帮助中心的editing help。 Stack Overflow 上的格式设置与其他站点不同。您的帖子看起来越好，其他人就越容易阅读和理解。
-
不确定这应该怎么做？无法创建表格，因为不允许使用 HTML 表格。
-
您的列将不再被评估为 int，而是对象。可以吗？
-
是的，此时它不再需要是 int，因为我将使用 .render() 推送到 HTML
-
我相信我创建了一个解决方案......现在测试......如果它有效，将提供答案
