Angular JS ng-repeat nested array

Question

I am trying to iterate array using ng-repeat, but not getting proper output.

<table>
   <tr>
     <th>Index</th>
     <th>Items</th>
   </tr>
   <tr ng-repeat="li in list">
     <td ng-repeat="(key,value) in li">{{key}}</td>
     <td ng-repeat="(key,value) in li">{{value}}</td>
   </tr>
</table>


$scope.list = [
        {"foo": ["item1", "item2"]},
        {"bar": ["item1", "item2"]}
    ];

Expected output:

Index   Items
foo    item1
foo    item2
bar    item1 
bar    item2

Actual output:

Index   Items
foo ["item1","item2"]
bar ["item1","item2"]

Anyone help me out to print the exact key,value of list.

You could create an custom filter or function that will simplify the result. That will also get rid of nested ng-repeat's

$scope.simplyfiedList = [];

$scope.list.forEach(function(item){
  Object.keys(item).map(function(key){
    item[key].map(function(i){
      $scope.simplyfiedList.push({key: key, value: i});
    })
  })
});

Html

<table class="table table-responsive">
  <tr>
    <th>Index</th>
    <th>Items</th>
  </tr>
  <tr ng-repeat="item in simplyfiedList">
    <td>{{item.key}}</td>
    <td>{{item.value}}</td>
  </tr>
</table>

Given the structure of your data you'd probably have to do something like this.

<div ng-repeat="li in list">
    <div ng-repeat="(key, itemArray) in li">
        <tr ng-repeat="item in itemArray">
            <td>{{key}}</td>
            <td>{{item}}</td>
        </tr>
    </div>
</div>

I didn't test it and also I wouldnt recommend it. I'd rather write a function that flattens the data.
