ColumnHelper docs?

So I'm reading docs on Column Defs and I see they use the

createColumnHelper

createColumnHelper

const columnHelper = createColumnHelper<Person>()

const columnHelper = createColumnHelper<Person>()

Is there more docs on the ColumnHelper object that is created from this? I want to see more information about how to use the

columnHelper.accessor()

columnHelper.accessor()

and

columnHelper.group()

columnHelper.group()

functions
