怎么在这个页面把前两列设置成能输入的文本框啊

[南笙ll]

columns:[
{id:"userName",dataType:"string",name:"userName",textMember:"text",caption:"用户名",allowEditing:true,align:"center",dataAlign:"center",width:"40%"},
{id:"securityInformation",dataType:"string",name:"securityInformation",textMember:"text",caption:"故障信息",align:"center",dataAlign:"center",width:"40%"},
{id:"securityDiagnosis",dataType:"string",name:"securityDiagnosis",textMember:"text",caption:"故障诊断",
align:"center",dataAlign:"center",width:"20%",
readOnly : true,
renderCell : function(p_item, $p_cell) {
var btn = $("<img src='resources/images/detailBtn.png'>");
$p_cell.addClass("pointer");
$p_cell.html(btn);
$p_cell.on("click", p_item, me.controller._detailBtn_onclick);
}
}
