Sorting CCK created documents using weight field?

I created a content type using CCK. It has an extra 'weight' field (integer type) which is used to sort the documents. Documents with bigger number show in bottom and vice versa. But how would I sort and display the documents without showing the weight field? In creaing Views, is there a way to use a field of the document but not showing in the View (without using php code)?

EDIT -- I found that it can be easily done by using Sort criteria. Then, the weight field is used as sort criteria, but not shown in the display.
