Column列布局

　　Ext.layout.container.Column对应面板布局layout配置项的名称为Column，支持属性columnWidth，每一个加入到容器中的子面板都可以通过columnWidth配置项指定百分比或使用width配置项指定固定值来确定列宽

　　width配置项是以像素为单位的固定列宽，必须是大于或等于1的数字。columnWidth配置项是以百分比为单位的相对宽度，必须是大于0小于1的小数，例如.25

　　1、指定固定列宽

    <title>Ext.layout.container.Column示例</title>
    <link href="ext-4.0.7-gpl/resources/css/ext-all.css" rel="stylesheet" type="text/css" />
    <script src="ext-4.0.7-gpl/bootstrap.js" type="text/javascript"></script>
    <script type="text/javascript">
        Ext.onReady(function () {
            Ext.create("Ext.panel.Panel", {
                title: "Ext.layout.container.Column示例",
                frame: true,
                width: 300,
                height: 200,
                renderTo: Ext.getBody(),
                bodyPadding: 5,
                layout: "column",
                defaults: {
                    bodyStyle: "background-color:#FFFFFF;padding:15px",
                    frame: true,
                    height: 100
                },
                items: [{
                    title: "子面板一",
                    width:100,
                    html: "子面板一"
                }, {
                    title: "子面板二",
                    width: 100,
                    html: "子面板二"
                }]
            });
        });
    </script>
</head>
<body>
</body>
</html>

　　2、使用百分比指定列宽

代码：

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.layout.container.Column示例</title>
    <link href="ext-4.0.7-gpl/resources/css/ext-all.css" rel="stylesheet" type="text/css" />
    <script src="ext-4.0.7-gpl/bootstrap.js" type="text/javascript"></script>
    <script type="text/javascript">
        Ext.onReady(function () {
            Ext.create("Ext.panel.Panel", {
                title: "Ext.layout.container.Column示例",
                frame: true,
                width: 300,
                height: 200,
                renderTo: Ext.getBody(),
                bodyPadding: 5,
                layout: "column",
                defaults: {
                    bodyStyle: "background-color:#FFFFFF;padding:15px",
                    frame: true,
                    height: 100
                },
                items: [{
                    title: "子面板一",
                    columnWidth: .3
                }, {
                    title: "子面板二",
                    columnWidth: .7
                }]
            });
        });
    </script>
</head>
<body>
</body>
</html>

　　3、固定值与百分比结合使用

代码：

<html xmlns="http://www.w3.org/1999/xhtml">

    <script src="ext-4.0.7-gpl/bootstrap.js" type="text/javascript"></script>
    <script type="text/javascript">
        Ext.onReady(function () {
            Ext.create("Ext.panel.Panel", {
                title: "Ext.layout.container.Column示例",
                frame: true,
                width: 400,
                height: 200,
                renderTo: Ext.getBody(),
                bodyPadding: 5,
                layout: "column",
                defaults: {
                    bodyStyle: "background-color:#FFFFFF;padding:15px",
                    frame: true,
                    height: 100
                },
                items: [{
                    title: "子面板一",
                    width: 100
                }, {
                    title: "子面板二",
                    columnWidth: .3
                }, {
                    title: "子面板三",
                    columnWidth: .7
                }]
            });
        });
    </script>
