Use of rowspan to group hierarchical data

Question

Is it possible to group data (using rowspan as explained here) in a table rendered with angularjs. Data is hierarchical, with state having many counties

Answer 1

This variant of KayakDave's answer improves the structuring by pulling the first nested row out to share the of the header:

    
      {{st.name}}
      {{county[0].name}}
    
    
       {{county.name}}
