ColumnHelper docs?

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

createColumnHelper

createColumnHelper

createColumnHelper

createColumnHelper to create their columns.
Docs: https://tanstack.com/table/v8/docs/guide/column-defs

const columnHelper = createColumnHelper<Person>()

const columnHelper = createColumnHelper<Person>()

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()

columnHelper.accessor()

columnHelper.accessor() and

columnHelper.group()

columnHelper.group()

columnHelper.group()

columnHelper.group() functions
