Reformatting Portal Entity List Column Values

I am trying to reformat the values for specific columns in my portal Entity List so that all whole number/currency fields have matching formats. The format I am aiming for will have all number fields in my entity list to have 0 currency precision, commas where necessary, and a $ symbol for currency fields. Some of my number fields already fulfill this requirement, but I have a couple whole number fields that need to match my specifications.

Ex. Whole Number column in my Entity List, want each record in the column to have a comma (11,859, 10,612, 98,842, 72,018)

Although it is possible to delete the whole number fields and replace them with currency fields of the same names, the whole number fields are linked to numerous forms and workflows which would all have to be remapped. I felt that this was unnecessary as their functionality in my CRM was fine and my need is purely visual for the portal. I have tried using custom Javascript from different CRM Portal articles to achieve what I need, but did not have enough information to get me to the finish line.

What would be the best way to accomplish the numerical formatting I need for my Entity List? Would custom Javascript be the best path for this, or would using a class like entityview in Liquid Templates be better suited for my request? 

Thanks everyone!
