Is there a way in Python to make a row of an HTML table multi-lined?

Question

I have a Python script that constructs a pandas DataFrame from API data, which I then convert to a pretty_html_table that will be the body of an email. In one of the rows, I have data containing an address. It is formatted as follows

Street Address: 123 Street Ave City: City State: ST Postal: 12345 

The HTML line breaks are a part of the string and thus aren't encoded, so in the email, it is all in that one line as shown above. I would like to have each element be on its own line within the same row (essentially have those tags actually do what they're supposed to do)

from pretty_html_table import build_table
import pandas

table = pandas.DataFrame({
   'Label': ["Name", "Address", "Item", "Contact Email", "Date"],
   'Info': ["", "", "", "", ""]
})

table.loc[0, 'Info'] = foo
table.loc[1, 'Info'] = foo
table.loc[2, 'Info'] = foo
table.loc[3, 'Info'] = foo
table.loc[4, 'Info'] = foo

pretty_table = build_table(table, "green_dark")

I can just replace the tags with whitespaces and make the string a little neater, but I would prefer for it to be on separate lines without making 4 separate rows.

{Comment from furas copied from Staging Ground}: it prints   because pandas (using df.to_html() in this place in source code) converts to   and browser/email displays it as string  , and it doesn't treat it as HTML tag. You may test print( table.to_html() ) and you should see instead of in HTML — Abra

{Comment from furas copied from Staging Ground}: based on source code you can use build_table(..., escape=False) and it will not convert   to   — Abra

@Abra thanks for the tedious work of migrating these comments, there should be a feature for that. — julaine

pretty_html_table escapes HTML by default. After building the table, just unescape the   tags:

html_table = build_table(table, "green_dark")
html_table = html_table.replace("&lt;br&gt;", "<br>")

Now the   tags render as real line breaks in your email.

Use build_table(..., escape=False).

escape controls whether html-sequences in data will be escaped or not. Escaping is obviously the default because of security. Read about Cross-Site-Scripting (XSS) before you think about enabling this in a web-context.

According to the source code of build_table this parameter gets passed to the escape-parameter of the underlying pandas .to_html call, which does the same thing, with the same default.

So use df.to_html(..., escape=True) if you are using pandas directly.
