Passing callable classes to addColumn

[recursivetree]

Summary of problem or feature request

After upgrading our app to laravel-datatables 9.21 and above, you can't pass a class implementing __invoke() to addColumn. While this has never been supported according to the docs, it has worked until now.

In our project, we used this to share common columns across multiple tables.

Instead of allowing everything that's callable, only Closures are passed through. It should be an easy fix to allow everything callable again.
