HTML to hide Table Columns on Billing Page

[TotalChoiceNate]

Good afternoon,

 

I am attempting to hide a couple column rows on the billing checkout page and not having any luck. Anyone more experienced have any ideas?

 

Basically, what we are running in to, is that we want to allow them to key in an account number, but not give them the ability to change that account number on a product by product basis (hence the need to hide the column rows that are generated.) Screenshot example is attached.
