你也可以这样做
检查提琴：

var userStore = Ext.create('Ext.data.Store', {
    data: [{
        "id": 1,
        "abbr": "AL",
        "name": "Alabama",
        "completed":false
    }, {
        "id": 2,
        "abbr": "AK",
        "name": "Alaska",
        "completed":false
    }, {
        "id": 3,
        "abbr": "AZ",
        "name": "Arizona",
        "completed":false
    }]
});

Ext.create('Ext.grid.Panel', {
    renderTo: document.body,
    store: userStore,
    width: 400,
    height: 200,
    title: 'Application Users',
    columns: [{
        width: 25,
        align: 'left',
        xtype: 'checkcolumn',
        tdCls: 'checkBoxColum',
        dataIndex: 'completed',
        renderer: function (value, meta, record, row, col) {
            /* Permission Check */
            var me = this;

            if(record.data.id==1)
            {
                meta['tdCls'] = 'x-item-disabled';
            }else
            {
                meta['tdCls'] = '';
            }
            return new Ext.ux.CheckColumn().renderer(value);
        }
    }, {
        text: 'name',
        width: 100,
        sortable: false,
        hideable: false,
        dataIndex: 'name'
    }]
});

检查一下这个提琴

我已经使用编辑器复选框和复选列完成了这项工作。

我的ExtJS 4解决方案

{
   xtype: 'checkcolumn',
   dataIndex: 'Check',
   width: 30,
   renderer: function (value, metaData, record) {
       return record.get('isDisabled') ? '' :
              (new Ext.grid.column.CheckColumn()).renderer(value);
   }
}

需要将下一个设置添加到网格：

selModel: Ext.create('Ext.selection.CellModel', {
    mode: 'SIMPLE'
}),
