从Outlook中的HTML表提取文本

我需要从一个HTML表中提取值，该表每周都会收到电子邮件。我的循环是检查表的指定文件夹中的每封电子邮件，因为有一些现有的电子邮件包含我想要捕获的信息。最终，这些数据将被推送到Pandas Dataframe 中进行额外的操作。
该表有4个标题列，但5个数据列，这是造成各种错误的Pandas。下面的代码让我接近最终结果，但仍然有问题。数据被填充为1x 24在XLSX文件。我需要的数据在5x 5，但不知道我如何才能完成这一点与标题行只有4列。

import win32com.client
import pandas as pd
from bs4 import BeautifulSoup

# email specs
outlook = win32com.client.Dispatch('outlook.application')
mapi = outlook.GetNamespace("MAPI")
inbox = mapi.GetDefaultFolder(6).Folders["TestFolder"]
messages = inbox.Items

# read email
for message in messages:
    body_content = message.HTMLBody
    bs = BeautifulSoup(body_content, features="lxml")
    table = bs.find_all("table")
    for row in table:
        r = row.find_all('span')
        df = pd.DataFrame(r)

    # save dataframe
    df.to_excel('df.xlsx')

HTML表格文件示例如下-

<html xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:w="urn:schemas-microsoft-com:office:word" xmlns:m="http://schemas.microsoft.com/office/2004/12/omml" xmlns="http://www.w3.org/TR/REC-html40"><head>

假设body_content是样本数据，并且每个电子邮件消息只有一个表（或者目标表是任何给定消息中的第一个表）：

# get table
bs = BeautifulSoup(body_content, features="html.parser")
tables = bs.find_all("table")
table = tables[0]  # assumes it is always the first table in any message

# get table data
records = []
rows = table.findAll("tr")
for row in rows:
    cells = row.findAll("td")
    row_data = []
    for cell in cells:
        val = cell.find("p", attrs={"class": "MsoNormal"})
        try:
            row_data.append(val.text.strip())
        except AttributeError:
            row_data.append(None)
    if not all(v is None for v in row_data):  # don't add empty row like end of sample data
        records.append(row_data)

# since there are only four column headers, we will extract these out and add an extra one
headers = records.pop(0)
headers.append("Unknown Extra Column")

# create pandas dataframe
df = pd.DataFrame(records, columns=headers)

对于示例数据，Dataframe应如下所示：

Asset ID & Name Lead Participant ISO Determination ISO Comment  \
0           65133           XXXXXX            XXXXXX      XXXXXX   
1           69067           XXXXXX            XXXXXX      XXXXXX   
2           69070           XXXXXX            XXXXXX      XXXXXX   

  Unknown Extra Column  
0               XXXXXX  
1               XXXXXX  
2               XXXXXX

您需要更改循环中某些内容的嵌套，但这适用于所提供的示例数据。
