Hi I followed this link (https://community.snowflake.com/s/article/How-to-include-query-results-in-Snowflake-email-alert-notifications) and now have a stored procedure on Snowflake that is converting a table into HTML and adding it to an alert email so people are aware of any failures / errors with any tasks / copy commands that we run into. The stored procedure bellow is working fine but am getting a table with no border lines:

CREATE OR REPLACE PROCEDURE ERRORS_ALERTS(
    email_integration_name STRING,
    email_address STRING
) 
RETURNS STRING
LANGUAGE PYTHON
RUNTIME_VERSION = 3.10
PACKAGES = ('snowflake-snowpark-python', 'pandas', 'tabulate')
HANDLER = 'main'
AS $$

import snowflake.snowpark
import pandas

def main(
  session: snowflake.snowpark.Session,
  email_integration_name: str,
  email_address: str
) -> str:
    table_pandas_df: pandas.DataFrame = session.table("logs").to_pandas()
    table_as_html: str = table_pandas_df.to_markdown(
      tablefmt="html",
      index=False
    )
    email_as_html: str = f"""
        <p>Today's loading errors report</p>
        <p>{table_as_html}</p>
    """
    success: bool = session.call(
      "SYSTEM$SEND_EMAIL",
      email_integration_name,
      email_address,
      'Daily loading errors report',
      email_as_html,
      'text/html'
    )

    return "Email sent successfully" if success else "Sending email failed"

$$;

Whenever I run the stored procedure above I get an email with the table below in the body:

Any tips on how I can add some code to add border lines and enhance the formatting of this table?
