Bug 32597: Fix table display of OPAC article requests

To test:
1. Enable ArticleRequests
2. Make some requests (two or more) on the OPAC and go to the user
   summary.
3. The table rows display horizontally.
4. Apply patch
5. Try step 2 again, the table should display correctly.

Note: I made some whitespace changes to make the markup look correct.
