带有组合框的网格面板作为列单元格编辑extjs

Question

我有一个包含三列的网格面板，我使用编辑器将这三列作为组合框，并添加了一个单元格编辑插件。我应该能够添加一行和 select 来自三个不同商店的组合框的值。问题是我无法添加没有默认网格存储的行。如何添加一行以查看 select 值的组合框列。 Here is the fiddle

Answer 1

"Grids are composed of two main pieces - a Ext.data.Store full of data and a set of columns to render."

您必须将商店添加到网格面板，然后尝试通过单击添加按钮向商店添加一行。我已经修改了代码，现在可以使用了。

Ext.application({
    models: [
        'OneModel',
        'TwoModel',
        'ThreeModel'
    ],
    views: [
        'MyGridPanel'
    ],
    name: 'combo',

    launch: function() {
        Ext.create('combo.view.MyGridPanel', {renderTo: Ext.getBody()});
    }

});

Ext.define('combo.view.MyGridPanel', {
    extend: 'Ext.grid.Panel',
    alias: 'widget.mygridpanel',

    requires: [
        'combo.view.MyGridPanelViewModel',
        'combo.view.MyGridPanelViewController',
        'Ext.grid.column.Column',
        'Ext.form.field.ComboBox',
        'Ext.view.Table',
        'Ext.toolbar.Toolbar',
        'Ext.button.Button',
        'Ext.grid.plugin.CellEditing'
    ],
    store:Ext.create('Ext.data.Store',{
        fields:[{   
            name:'One',
