Accessor key does not have the same typing as Form's name key

[Bahnasawy]

TanStack Table version

v8.21.3

Framework/Library version

React v19.2.7

Describe the bug and the steps to reproduce it

ColumnDef defines accessorKey as

accessorKey: (string & {}) | keyof TData;

Which causes accessorKey not to produce the same suggestions as a form field's name key in tanstack form.

My suggestion is to define accessorKey as

accessorKey: DeepKeys<TData>;
