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' },
{ name: 'Bart', email: 'bart@simpsons.com', phone: '555-222-1234' },
{ name: 'Homer', email: 'home@simpsons.com', phone: '555-222-1244' },
{ name: 'Marge', email: 'marge@simpsons.com', phone: '555-222-1254' }
]
});
Ext.create('Ext.grid.Panel', {
renderTo: Ext.getBody(),
store:userStore,//数据源
width: 400,
height: 200,
title: 'Application Users',
columns: [
{
text: 'name',
width: 100,
sortable: false,
hideable: false,
dataIndex: 'name'
},
{
text:'Email Address',
width: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

效果图：
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：
