<html>
  <head><title>Arrar Read</title>

    Here is an ExtJs 4 example: (working fiddle)

    var arrayD = [
    ['Jary Garcia', 'MD'],
    ['Arron, Baker', 'VA'],
    ['Susan Smith', 'DC'],
    ['Mary Smith', 'DE'],
    ['Bryan Shanly', 'NJ'],
    ['Nyron Selgado', 'CA']
];

Ext.define('Person', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'name',  type: 'string'},
        {name: 'state',   type: 'string'}
    ]
});

var store = Ext.create('Ext.data.Store', {
     model: 'Person',
     data: arrayD 
});

var grid = Ext.create('Ext.grid.GridPanel', { //create a gridpanel
    title: 'First Grid',
    renderTo: Ext.getBody(),
    autoHeight: true,
    width: 250,
    store: store,
    columns: [
        {
            header: 'Full Name',
            sortable: true,
            dataIndex: 'name'},
        {
            header: 'State',
            dataIndex: 'state'
        }
    ]
});

console.debug('everything executed');​

    You can download your own version and put it in a webserver or use one of these for js:

    //for production
<script src="http://cdn.sencha.io/ext-4.1.1-gpl/ext-all.js"></script>
//for debug => isn't minified
<script src="http://cdn.sencha.io/ext-4.1.1-gpl/ext-all-debug.js"></script>
//for development => isn't minified, logs errors and warnings to the console.
<script src="http://cdn.sencha.io/ext-4.1.1-gpl/ext-all-dev.js"></script>

    for css use:

    <link rel="stylesheet" type="text/css" href="htpp://cdn.sencha.io/ext-4.1.1-gpl/resources/css/ext-all.css"/>
