Should data be flattened before passing to table?

[egertaia]

Hello.
We currently have a situation where data object has an array of years under it which also have data that should be shown within table.

We calculate the columns based on available years on application but currently the only way to actually get value of cell is trough row original property.

Should we try to denormalize data before passing to table?

So from this
data:[ {name: "ABC", years: [{from :2020, to:2022, price: 200}]}]

To

data:[ {name: "ABC", 2020price: 200}]

If the plan is to make rows editable as well.
