title: Adding Disclosure Buttons to a Table when using Data.plist
body: <p>I've created a table from a data.plist and was trying to figure out how to add a disclosure button at the second level-to-third level table.  It would be used to add a UIView "credits" to the student artists who made the picture.  However, I need to make sure that the name can change as the table will house different files from different students.  So for example, cases 1-3 would all be Aubrey's work, and cases 4-6 would be Josh's, etc.</p>
  
  <p>Any help would be great.</p>
