Scott, Thanks for the speedy reply!
The array approach was what I originally came up with but it felt a bit raw. Seems like there should some sort of <%= content_for ... %> approach or similar that would be more elegant. It's not really an issue of performance since all the data needed will be in memory when the collection is initially loaded. It's about trying not to create this gawd-awful ugly view with a dozen <% @instances.each do |instance| %> calls to loop through the model objects each time I want to create a row of data. It just "feels" wrong and I'm hoping someone has tackled this before and come up with a clever solution.
