title: How to display table with grouping
body: <p>I need to create a table that can group by a object property. I am unable to use ngTable for this so I am hoping there is a way to do it with a filter or nested ng-repeats.</p>

  <pre><code>"CompanyId": "40",
  "CompanyName": "XEREX",
      "CompanyEmployees": {
          "_id": "544",
           "CompanyEmployeeFirstName": "Taylor",
           "CompanyEmployeeLastName": "Bartlett",
           "CompanyEmployeeState": "Vermont"
  </code></pre>
  
  <p>the table needs to show a list of the Employees Names and they need to be grouped by there State. </p>
