ext.net2.0 GridPanel 实现自动换行

参考加入以下代码即可实现：

<style type="text/css">
.x-grid3-row td, .x-grid3-summary-row td
{
vertical-align: middle;
}
</style>

var template = '<span style="white-space:normal;">{0}</span>';
var pctChange = function (value) {
return Ext.String.format(template,value);
};

<ext:Column ID="Column4" runat="server" DataIndex="WEEK1" Header="第一周(简述)" Align="left" Width = "130px">
<Renderer Fn="pctChange" />
</ext:Column>
