accessor function returning number gives Typescript error

The weight is a number, If I have this column: 
 internalSchemaClassesColumnHelper.accessor("weight", {
    id: 'weight',
    header: 'Weight',
    cell: (info) => info.getValue()
  }),
 internalSchemaClassesColumnHelper.accessor("weight", {
    id: 'weight',
    header: 'Weight',
    cell: (info) => info.getValue()
  }),
It would give a long TS error on the Table comoponent: 
 Type 'ColumnDefBase<Class, number> & StringHeaderIdentifier' is not assignable to type 'AccessorFnColumnDefBase<Class, string> & IdIdentifier<Class, string>'.
        Property 'accessorFn' is missing in type 'ColumnDefBase<Class, number> & StringHeaderIdentifier' but required in type 'AccessorFnColumnDefBase<Class, string>'.
 Type 'ColumnDefBase<Class, number> & StringHeaderIdentifier' is not assignable to type 'AccessorFnColumnDefBase<Class, string> & IdIdentifier<Class, string>'.
        Property 'accessorFn' is missing in type 'ColumnDefBase<Class, number> & StringHeaderIdentifier' but required in type 'AccessorFnColumnDefBase<Class, string>'.
The error goes away if I change the first argument of accessor from "weight" to (row) => row.weight.toLocaleString() The question: Should the accessor function always return string?
