Aslagle:reactive-table setting my collection fields

I managed to get my table showing up, but I’m wondering:
I have the following property on my collection: reference. If I want to display that property in portuguese on my table I just need to declare it like this:

 key: 'reference',
label: 'Referencia'

But what if I have 30+ properties, I wonder If I can make a map on an external .js file, something like:

const mapping = {
"reference": "Referencia",
"type": "Tipo",
"currency": "Moeda"
(. . .)

and apply on reactive-table settings
is that possible? if yes how?
Thanks in advance
