title: How to get the cell value from ng-grid
body: <p>I am a beginner of AngularJS. I study the demo of ng-grid and have a question.</p>
  
  <p>index.html</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html ng-app="myApp"&gt;
  
  &lt;head&gt;
  &lt;meta charset="utf-8" /&gt;

  &lt;script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.2/angular.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="http://angular-ui.github.com/ng-grid/lib/ng-grid.debug.js"&gt;&lt;/script&gt;
  &lt;script src="app.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  
  &lt;body ng-controller="MyCtrl"&gt;
      &lt;div class="gridStyle" ng-grid="gridOptions"&gt;&lt;/div&gt;
      &lt;div class="selectedItems"&gt;{{mySelections}}&lt;/div&gt;&lt;br&gt;&lt;br&gt;
  
  &lt;/body&gt;
  
  &lt;/html&gt;
  </code></pre>
  
  <p>app.js</p>
  
  <pre><code>var app = angular.module('myApp', ['ngGrid']);
  app.controller('MyCtrl', function($scope) {
  $scope.mySelections = [];
  $scope.myData = [{name: "Moroni", id: 1},
                   {name: "Tiancum", id: 2},
                   {name: "Jacob", id: 3},
                   {name: "Nephi", id: 4},
                   {name: "Akon", id: 5},
                   {name: "Enos", id: 6}];
  $scope.gridOptions = { 
  data: 'myData',
  selectedItems: $scope.mySelections,
  multiSelect: true 
  };
  
  //$scope.mySelections_id = $scope.mySelections.length;
  
  });
  </code></pre>
  
  <p>When I select the first row, the div of selectedItems will show [{"name":"Moroni","id":1}]. the result is OK. If I just want to get the value of cell [id] from selected row, how do I modify my code?</p>
