以下是功能网格的示例，其中包含ID，名称，说明，项目，发布和相关用户故事的列。

Ext.define('CustomApp', {
    extend: 'Rally.app.App',
    componentCls: 'app',

    launch: function() {
        console.log("PI GRID");
        Ext.create('Rally.data.WsapiDataStore', {
            model: 'PortfolioItem/Feature',
            fetch: ['FormattedID','Name','Description','UserStories','Release','Project'],
            pageSize: 100,
            autoLoad: true,
            listeners: {
                load: this._onDataLoaded,
                scope: this
            }
        });
    },

    _createGrid: function(features) {
         this.add({
            xtype: 'rallygrid',
            store: Ext.create('Rally.data.custom.Store', {
                data: features,
                pageSize: 100
            }),

            columnCfgs: [
                {
                   text: 'Formatted ID', dataIndex: 'FormattedID', xtype: 'templatecolumn',
                    tpl: Ext.create('Rally.ui.renderer.template.FormattedIDTemplate')
                },
                {
                    text: 'Name', dataIndex: 'Name'
                },
                {
                    text: 'Description', dataIndex: 'Description'
                },
                {
                    text: 'Release', dataIndex: 'Release'

                    text: 'Project', dataIndex: 'Project'
                },
                {
                    text: 'Story Count', dataIndex: 'StoryCount'
                },
                {
                    text: 'User Stories', dataIndex: 'UserStories', 
                    renderer: function(value) {
                        var html = [];
                        Ext.Array.each(value, function(userstory){
                            html.push('<a href="' + Rally.nav.Manager.getDetailUrl(userstory) + '">' + userstory.FormattedID + '</a>')
                        });
                        return html.join(', ');
                    }
                }
            ]

        });
    },
    _onDataLoaded: function(store, data){
                var features = [];
                var pendingstories = data.length;
                Ext.Array.each(data, function(feature) {
                            var release = feature.get('Release');
                            var f  = {
                                FormattedID: feature.get('FormattedID'),
                                Name: feature.get('Name'),

                            var stories = feature.getCollection('UserStories');
                           stories.load({

                                callback: function(records, operation, success){
                                    Ext.Array.each(records, function(story){
                                        var number = story.get('DirectChildrenCount');  
                                        if (number == 0) {
