Ext.onReady(function(){
    // example of custom renderer function
    function pctChange(val){
        if(val > 0){
            return '<span style="color:red;">未激活</span>';
        }else if(val <= 0){
            return '正常';
        }
        return val;
    }
	var recordType = Ext.data.Record.create([ {
		name : 'id',
		type : 'float',
		mapping : 'id'
	}, {
		name : 'username',
		type : 'string',
		mapping : 'username'
	}, {
		name : 'pwd',
		type : 'string',
		mapping : 'pwd'
	}, {	
		name : 'state',
		type : 'float',
		mapping : 'state'
	}]);

    // create the data store
	var store = new Ext.data.Store( {
		proxy : new Ext.data.HttpProxy( {
			url : 'User/doGetUserList.action'
		}),

		// set up the JsonReader
		reader : new Ext.data.JsonReader( {
			root : 'list',
			id : 'id'
		}, recordType)
	});
    store.load();

	var sm = new Ext.grid.CheckboxSelectionModel( {
		singleSelect : false
	});
    // create the Grid
    var grid = new Ext.grid.GridPanel({
        store: store,
        columns: [
        	new Ext.grid.RowNumberer(),
            {id:'id',header: "id", width: 160, sortable: true, dataIndex: 'id'},
            {header: "姓名", width: 75, sortable: true, dataIndex: 'username'},
            {header: "密码", width: 75, sortable: true, dataIndex: 'pwd'},
            {header: "状态", width: 75, sortable: true, renderer: pctChange, dataIndex: 'state'},
            sm
        ]
    });
	grid.render('grid');
    grid.getSelectionModel().selectFirstRow();
});

运行后数据有多条，但是只显示一条
