angularjs - ng-repeat: access key and value from JSON array object

I have JSON Array object as shown below.

$scope.items = 
    [
    {Name: "Soap",  Price: "25",  Quantity: "10"},
    {Name: "Bag",   Price: "100", Quantity: "15"},
    {Name: "Pen",   Price: "15",  Quantity: "13"}
];

I want to get the keys and values separately using ng-repeat in angular.js. I have tried the following code but its not working.

<tr ng-repeat="(key, val) in items">
  <td>{{key}}</td> 
  <td>{{val}}</td>
 </tr> 

I believe the problem is with the braces '[' and ']'. Can anyone please suggest me how the issue can be resolved ?

Edited:

Thank you so much for the reply. I have tried your code and its working. But my real requirement is display the items as shown below.

Name     Price  Quantity
Soap        25  10
Bag        100  15
Pen         15  13

I am using some <tr> and <td> in html. But nothing getting displayd in screen. The codes are shown below.

<table>  
 <tr ng-repeat="item in items">
  <tr ng-repeat="(key, val) in item">
      <td>{{key}}</td>
      <td>{{val}}</td>
  </tr>
</tr> 
</table>

I know that <tr> inside of another <tr> is not permitted by html. I tried by best.But no luck. It will be great if you could help me in this. Thanks in advance.

You've got an array of objects, so you'll need to use ng-repeat twice, like:

<ul ng-repeat="item in items">
  <li ng-repeat="(key, val) in item">
    {{key}}: {{val}}
  </li>
</ul>

Edit:

Note that properties order in objects are not guaranteed.

<table>
    <tr>
        <th ng-repeat="(key, val) in items[0]">{{key}}</th>
    </tr>
    <tr ng-repeat="item in items">
        <td ng-repeat="(key, val) in item">{{val}}</td>
    </tr>
</table>
