How to show table information inside Notification email

Hey guys,
So I have a table inside the Event doctype and a notification email set for when a new event is added.

Inside the notification email I have added the following code to pull the table information:

<h4>Guest details</h4>
{{ doc.guests }}

The result inside the e-mail is like this although the data is properly entered in the table.:

Guest details

[, ]

Please note, the table is a link from another doctype.

I;m also facing Same Issue Kindly anyone help me to resolve this
