Describe the bug and the steps to reproduce it

Similar to issue https://github.com/TanStack/table/issues/5135 (for AccessorKeyColumnDefBase), in this case the error comes from AccessorFnColumnDefBase.

It seems to happen when several columns have different return types in their accessorFn, this error happens:

Exported variable 'Columns' has or is using name 'AccessorFnColumnDefBase' from external module "/node_modules/@tanstack/table-core/build/lib/types" but cannot be named.
