Extjs ComboBox里面的网格

Question

我有一个带有一些数据的网格(用户列表).对于每一行,我有许多操作,例如更新,删除,激活,暂停,查看您为其命名的订单.

我没有放置那么多的按钮来填充多个400-500像素,而是放置一个组合框,并将动作应用于每个字段.

问题是我不能简单地在列行中渲染一个组合框,或者我错过了什么？有人可以对此有所了解吗？

new Ext.grid.GridPanel({
    region: 'center',
    id: 'usersGrid',
    store: store,
    stripeRows: true,
    autoExpandColumn: 'username',
    columns: [{
            // username
        },{
            // email
        },{
            // last seen
        },{
            //  actions combo, it won't show
            header: '',
            width: 220,
            fixed: true,
            hideable: false,
            dataIndex: 'actions',
            renderer: new Ext.form.ComboBox({
                store: new Ext.data.SimpleStore({
                    id: 0,
                    fields: ['abbr', 'action'],
                    data: [
                        ['suspend', 'Suspend'],
                        ['activate', 'Activate'],
                        ['update', 'Update'],
                        ['delete', 'Delete']
                    ]
                }),
                displayField: 'action',
                valueField: 'abbr',
                mode: 'local',
                typeAhead: false,
                triggerAction: 'all',
                lazyRender: true,
                emptyText: 'Select action'
            })
        }
    ]
});

1. 将网格转换为可编辑网格
2. 在列中添加编辑器配置而不是"渲染器".在下面找到更改的代码.

new Ext.grid.EditorGridPanel({
    region: 'center',
    id: 'usersGrid',
    store: store,
    stripeRows: true,
    autoExpandColumn: 'username',
    columns: [{
        // username
    }, {
        // email
    }, {
        // last seen
    }, {
        //  actions combo, it won't show
        header: '',
        width: 220,
        fixed: true,
        hideable: false,
        dataIndex: 'actions',
        editor: {
            xtype: 'combo',
            store: new Ext.data.ArrayStore({
                fields: ['abbr', 'action'],
                data: [
                    ['suspend', 'Suspend'],
                    ['activate', 'Activate'],
                    ['update', 'Update'],
                    ['delete', 'Delete']
                ]
            }),
            displayField: 'action',
            valueField: 'abbr',
            mode: 'local',
            typeAhead: false,
            triggerAction: 'all',
            lazyRender: true,
            emptyText: 'Select action'
        }
    }]
});
