var sm = new Ext.grid.CheckboxSelectionModel();
var cm = new Ext.grid.ColumnModel([
sm,
{header:"编号",width:90,sortable:true,dataIndex:"id"},
{header:"标题",width:90,sortable:true,dataIndex:"title"},
{header: "作者", width: 100, sortable: true, dataIndex: 'username'},
{header: "登录次数", width: 90, sortable: true, dataIndex: 'loginTimes'}
]);

xml代码：
<topics>
<results>2</results>
<row>
<id>1</id>
<title>测试</title>
<author>小王</author>
<loginTimes>3</loginTimes>
</row>
<row>
<id>2</id>
<title>新年好</title>
<author>williamraym</author>
<loginTimes>13</loginTimes>
</row>
</topics>
运行结果：
如果myReader使用
var myReader = new Ext.data.XmlReader({
record:"row"
},["id","title","author","loginTimes"]);*/
时，下方“作者”的dataIndex的值也应相应地改为"author".
