combobox - 网格内的 Extjs ComboBox

Question

我有一个包含一些数据的网格(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、查看您命名的订单。

而不是放置如此多的按钮，这些按钮将填充超过 400-500像素 我想放置一个组合框，其中的 Action 应用于每个字段。

问题是我不能像那样简单地在列行中呈现组合框，或者我遗漏了什么？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. Convert Grid to Editable Grid
2. Add editor config in columns instead of 'renderer'. Find below the altered code.

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'
        }
    }]
});
