How to make subrows column accessors different than the main?

[TitoSniberb]

Let's say my main data objects looks like [{ a: 'a', b: 'b', subRows: [{ c: 'c', d: 'd' }] }]

How could I make it so when expanding the subRows, the props c and d are rendered as accessor keys for the subRows?

const columns = [
  {
    accessorKey: 'a'
  },
  {
    accessorKey: 'b'
  },
]

@TitoSniberb have you found an answer to that?
