javascript - Create Table from JSON Data with angularjs and ng-repeat

Question

I have the following data as JSON:

{
  "Workout1": {
    "Name": "First",
    "Rounds": [
      {
        "Exercises": [
          {
            "Name": "Exercise1",
            "Repeat": 10
          },
          {
            "Name": "Exercise2",
            "Repeat": 10
          },
          {
            "Name": "Exercise3",
            "Repeat": 10
          }
        ]
      },
      {
        "Exercises": [
          {
            "Name": "Exercise1",
            "Repeat": 20
          },
          {
            "Name": "Exercise2",
            "Repeat": 20
          },
          {
            "Name": "Exercise3",
            "Repeat": 20
          }
        ]
      },
      {
        "Exercises": [
          {
            "Name": "Exercise1",
            "Repeat": 30
          },
          {
            "Name": "Exercise2",
            "Repeat": 30
          },
          {
            "Name": "Exercise3",
            "Repeat": 30
          }
        ]
      }
    ]
  }
}

and I want to display it as a html table with angularjs and ng-repeat. so that I get the following table:

<table class="table">
    <tr>
        <th>Round1</th>
        <th>Round2</th>
        <th>Round3</th>
    </tr>
    <tr>
        <td>10 Exercise1</td>
        <td>20 Exercise1</td>
        <td>30 Exercise1</td>
    </tr>
    <tr>
        <td>10 Exercise2</td>
        <td>20 Exercise2</td>
        <td>30 Exercise2</td>
    </tr>
    <tr>
        <td>10 Exercise3</td>
        <td>20 Exercise3</td>
        <td>30 Exercise3</td>
    </tr>
</table>

my problem that the html table is working row-based. I can iterate with ng-repeat through my Rounds and then through my excercises but for creating a table I need always the first of each exercises then the second of each exercises and so on.

Can someone help me with this problem?

ps. if you have an idea for better layout for this data in json, your suggestions are welcome, I'm new to json (and angularjs).

The solution you are looking for is in Angular's official tutorial. In this tutorial Phones are loaded from a JSON file using Angulars $http service . In the code below we use $http.get to load a phones.json file saved in the phones directory:

var phonecatApp = angular.module('phonecatApp', []);   
phonecatApp.controller('PhoneListCtrl', function ($scope, $http) {
 $http.get('phones/phones.json').success(function(data) {
$scope.phones = data;
}); 
$scope.orderProp = 'age';
});

We then iterate over the phones:

<table>
  <tbody ng-repeat="i in phones">
    <tr><td>{{i.name}}</td><td>{{$index}}</td></tr>
    <tr ng-repeat="e in i.details">
       <td>{{$index}}</td>
       <td>{{e.foo}}</td>
       <td>{{e.bar}}</td></tr>
  </tbody>
