无法将DataFrame转为HTML表格：变量嵌入HTML失败问题

Let's break down what's going wrong here and fix it step by step:

The Root of the Problem #

Your line .format((Name,Body).to_html()) has two critical issues:

1. You’re wrapping Name (a string) and Body (a pandas DataFrame) into a tuple, then trying to call to_html() on that tuple. Tuples don’t have a to_html() method—this method only exists for pandas DataFrames.
2. The format() method expects separate arguments for each placeholder in your string, but you’re passing a single (invalid) value instead of matching the two placeholders in your template.

The Correct Approach #

First, convert your DataFrame to an HTML table string on its own, then pass both the name and this HTML string to format():

Name = "Tom"
Body = Email_Body_Data_Frame

# Convert the DataFrame to a properly formatted HTML table string
body_html = Body.to_html()

# Insert both variables into your HTML template
html = """\
<html> <head> </head> <body>
Hi {0} <br> <br> TEXT TEXT TEXT TEXT TEXT <br> <br> {1} <br>
TEXT TEXT TEXT TEXT TEXT TEXT
</body> </html>
""".format(Name, body_html)

What This Does #

• Body.to_html() takes your DataFrame and converts it into a complete HTML table snippet (with <table>, <tr>, <td> tags, etc.) that can be directly embedded into your email’s HTML structure.
• The format() method now receives two separate arguments: Name fills the {0} placeholder, and body_html fills {1}—exactly matching the two placeholders in your template.

I also removed the extra <br> after </body> in your template—this was invalid HTML, as body tags shouldn’t have content after they’re closed.
