除非更改值，否则如何避免网格单元格成为脏单元格，当我只是触摸时间单元格时，它会变成脏单元格，如何避免变脏，这是小提琴

这是我的网格，

Ext.application({
    name: 'Fiddle',

launch: function () {

var myStore = Ext.create('Ext.data.Store', {
    storeId: 'simpsonsStore',
    fields: ['busname', 'time', 'typebus',],
    data: [{
        busname: 'ABCD',
        time: '15:30:00',
        typebus: 'AC Volvo',

    }, {
        busname: 'aaa',
        time: '13:30:00',
        typebus: 'Seater',

    }, {
        busname: 'AAAA',
        time: '18:30:00',
        typebus: 'Sleeper',

    }, {
        busname: 'ABCD',
        time: '19:30:00',

试试这个方法 -小提琴

Ext.application({
  name: 'Fiddle',
  launch: function() {
    run();
    window.show();
  }
});

function run() {
  var myStore = Ext.create('Ext.data.Store', {

    }, {
