Table Inside a customer Field - How do display in Email the table?

We are sending emails to people that have data coming from SFDC in a custom field that look like this. Easchie leads has different values we want to present those as a table.

<table><tr><td>Access Code</td><td>Remaining Uses</td><td>Start Date</td><td>End Date</td></tr><tr><td>hh7zh-lgyal</td><td>2.0</td><td>2018-12-31 08:00:00</td><td>2019-12-30 08:00:00</td><td></table>

How do we get the email, to display the table? 

When we put in the token inside the email, it does not render the table. It just show as string of text.

It is not an option to create many fields with individual values as this is coming from another system into SFDC and then to MKTO.

Is there some addtional HTML we need to add into the field to render or inside the code of the email?
