extjs中如何选中grid中的行，并设置该行不可编辑

Ext.create('Ext.grid.Panel', {

  title: 'Simpsons',

  store: Ext.data.StoreManager.lookup('simpsonsStore'),

  columns: [

      { text: 'Name',  dataIndex: 'name' },

      { text: 'Email', dataIndex: 'email', flex: 1 },

      { text: 'Phone', dataIndex: 'phone' }

  ],

  listeners:{

      beforeedit:function(editor, e, eOpts){

          //return false//不可编辑

      return true//可编辑

      }

  },

  height: 200,

  width: 400,

  renderTo: Ext.getBody()

})

if (!Ext.grid.GridView.prototype.templates) {

Ext.grid.GridView.prototype.templates = {}

}

Ext.grid.GridView.prototype.templates.cell = new Ext.Template(

'<td class="x-grid3-col x-grid3-cell x-grid3-td-{id} x-selectable {css}" style="{style}" tabIndex="0" {cellAttr}>',

'<div class="x-grid3-cell-inner x-grid3-col-{id}" {attr}>{value}</div>',

'</td>'

)

添加如上代码，就可以选中了
