title: best practice for creating repeating cocoa UI element groups
body: <p>Anyone have any examples of methods for creating a UI with multiple (one or more) lines (groups) of UI elements?  There will be at least two different "groups" of elements (labels, text fields, check boxes, etc), but there will be common columns (headers).  The number of rows (lines) of elements is determined at run-time - there will be at least one, and possibly up to a dozen.  </p>
  
  <p>I'm sure I'll have to resize the containing window in some cases.  I think the typical case will be two or three lines, and the base layout will be sized for that.</p>
  
  <p>I'm sure I could do it all in direct code, but I'm wondering if there's some interface builder magic that would make this easier.</p>
  
  <p>Thanks!</p>
