此文章翻译的官方文章,感觉还是有一些地方不是很详细

效果图:

 Ext.onReady(function () {
            Ext.define('User', {
                extend: 'Ext.data.Model',
                fields: ['name', 'email', 'phone']
            });

            var userStore = Ext.create('Ext.data.Store', {
                model: 'User',
                //使用内联 数据
                data: [
                    { name: 'Lisa', email: 'lisa@simpsons.com', phone: '555-111-1224' },

            });
            Ext.create('Ext.grid.Panel', {
                renderTo: Ext.getBody(),
                store:userStore,//数据源
                 400,
                height: 200,
                title: 'Application Users',
                columns: [
                    {
                        text: 'name',
                         100,
                        sortable: false,
                        hideable: false,
                        dataIndex: 'name'
                    },
                    {
                        text:'Email Address',
                        150,
                        dataIndex: 'email',
                        hidden:false //隐藏了 这列 
                    },
                    {
                        text:'Phone Number',
                        flex:1,
                        dataIndex:'phone'
                    }
                ]
            });
        });

我们创建了一个表格面板渲染到了body中,并且告诉它从之前创建的userStore中取得数据,最后我们定义了表格面板有哪些列,用dataIndex属性配置表格中的列和User Model中的字段的对应关系,Name列宽度是100,不能排序也不能隐藏,Email Address列默认是隐藏的(可以通过其他列的菜单控制显示),Phone Number列自适应表格剩余的宽度

 =================================================================================

 Fit布局+Grid

在Fit布局中,子元素将自动填满整个父容器。注意:在fit布局下,对其子元素设置宽度是无效的。如果在fit布局中放置了多个组件,则只会显示第一个子元素。典型的案例就是当客户要求一个window或panel中放置一个GRID组件,grid组件的大小会随着父容器的大小改变而改变。

这里的Grid的数据类型使用ArrayStore

Fit布局Grid+ArrayStore

 测试fit布局下放两个panel,因为默认只能显示一个,另一个必须要隐藏,有些类似于Card布局,只显示一个Panel内的内容:
