My company currently uses 9-month leases for employees that need them.
I have an app set up that gives the employee a quote based on a number of factors, with the outcome looking like this:

I want this data to display in a table, as the "decal" is actually 2 amounts that need to paid all at once - $130 to put stickers on the car when it's received, and $50 to take them off when the vehicle is returned. Ideally displayed as below (with the extra columns added):

I'd also like if possible, to have the user select which month they want the costing to begin on. I want the first instance of the $130 to then show up in that month in the table. E.g. Instead of starting in Jul-19, begin in Dec-19.
I've had a few attempts at building a table into the email using HTML but can't get it configured properly.
