擴展grid------RowExpander.js

首先引入JS：RowExpander.js 這個文件可以在ext提供的example/grid找到

Ext.onReady(function(){

Ext.QuickTips.init();

var xg = Ext.grid;

// shared reader
var reader = new Ext.data.ArrayReader({}, [
{name: 'company'},
{name: 'price', type: 'float'},
{name: 'change', type: 'float'},
{name: 'pctChange', type: 'float'},
{name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'},
{name: 'industry'},
{name: 'desc'}
]);

[color=red] var expander = new xg.RowExpander({
tpl : new Ext.Template(
'<p><b>Company:</b> {company}</p><br>',
'<p><b>Summary:</b> {desc}</p>'
)
});[/color]

var grid1 = new xg.GridPanel({
store: new Ext.data.Store({
reader: reader,
data: xg.dummyData
}),
cm: new xg.ColumnModel([
[color=red] expander,[/color]
{id:'company',header: "Company", width: 40, sortable: true, dataIndex: 'company'},
{header: "Price", width: 20, sortable: true, renderer: Ext.util.Format.usMoney, dataIndex: 'price'},
