Views weight field renders incorrectly for users without "assign node weights" permission

On table views containing a Weight field displayed as a form element, users with the "assign node weights" permission will correctly see a draggable table:

However, users without the "assign node weights" permission still see the form submit button, as well as an empty column in the table:

(The empty column remains visible even when "Hide empty column" is selected in the view's style options.)

I believe this issue is due to the "assign node weights" access control being applied only to the weight-selection form fields, rather than to the entire views field handler. I've attached a patch that does the latter, removing the unwanted submit button and table column for users without the "assign node weights" permission:

When testing, be sure to clear all caches after applying the patch.
