Bug 7278: Follow up fixing display of item informaton on detail page

Fixes a display problem in the item table on staff detail page.

To test:
Add a record with 3 items:
- 1 with copynumber
- 1 with materials specified
- 1 with opac notes

Before patch the table will be broken a bit and the headings
don't match the contents (wrong sequence).
