group results

If I have a 1000 items and most are the same. How do I only show 1 unique line item.  So, instead of 1000 items it will show 23 unique lines?

You need to make an aggregate model. 

Check out this tutorial:…

You will not be able to group on your concatenated formula field - but you will be able to group by zip code. 

All fields you want to show on your table will have to be in the grouping section.  

Finally:  If all your fields on the table are on the parent (and grandparent) objects,  why not make your model on the parent objects?
