For your condition, you can use ng-if inside ng-repeat as Pankaj said in the comment.

  var app = angular.module('ExampleApp', []);
  app.controller('appController', ['$scope', function($scope) {
    $scope.p = {
      "info": [{
        "id": "11",
        "name": "brown",
        "description": "fasdfasd",
        "size": "fasdf",
        "color": "5a72fb",
        "created_at": "2015-09-08 22:33:33",
        "updated_at": "2015-09-08 22:33:33",
        "images": ['\"236.jpg\"','\"504.jpg\"','\"784.jpg\"']
      }, {
        "id": "13",
        "name": "fasdf",
        "description": "asdfghjkl",
        "size": "fasdf",
        "color": "5a72fb",
        "created_at": "2015-09-09 11:48:31",
        "updated_at": "2015-09-09 11:48:31",
        "images": ['\"910.jpg\"','\"504.jpg\"','\"784.jpg\"']
      }]
    }

  }]);
<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="utf-8">
  <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.18/angular.js"></script>
  <script src="http://www.jeasyui.com/easyui/jquery.easyui.min.js"></script>
  <script src="script.js"></script>
</head>

<body ng-app="ExampleApp">
  <div ng-controller="appController">
<div ng-repeat="x in p.info">
  {{ x.images[0] +" are first"}}
</div>
  </div>
</body>

</html>

Here is the working Link for your code

Hope it helps you to understand :)

There are many ways to do it. One way would be to use filter limitTo:1 with ng-repeat.

Try this

<tr ng-repeat="x in p | |limitTo:1">
    <td>
     {{ x.images }}
    </td>
</tr>

Well just doing the following will work:

<td>
    {{p[0]}}
</td>
