我是 AngularJS 的初学者。我研究了ng-grid的demo，有一个问题。

<body ng-controller="MyCtrl">
<div class="gridStyle" ng-grid="gridOptions"></div>
<div class="selectedItems">{{mySelections}}</div><br><br>
</body>
</html>
app.js
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;
});
当我选择第一行时，selectedItems 的 div 将显示 [{"name":"Moroni","id":1}]。结果没问题。如果我只想获取所选行中单元格[id]的值，如何修改我的代码？
这是Plunker
