Flex grid 复杂表头
第一种 最简单的两重表头
code 如下:
<?xml version="1.0"?> <mx:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="init()"> <fx:Script> <![CDATA[ import mx.collections.ArrayCollection; [Bindable] private var dpFlat:ArrayCollection = new ArrayCollection([ {Region:"Southwest", Territory:"Arizona", Territory_Rep:"Barbara Jennings", Actual:38865, Estimate:40000}, {Region:"Southwest", Territory:"Arizona", Territory_Rep:"Dana Binn", Actual:29885, Estimate:30000}, {Region:"Southwest", Territory:"Central California", Territory_Rep:"Joe Smith", Actual:29134, Estimate:30000}, {Region:"Southwest", Territory:"Nevada", Territory_Rep:"Bethany Pittman", Actual:52888, Estimate:45000}, {Region:"Southwest", Territory:"Northern California", Territory_Rep:"Lauren Ipsum", Actual:38805, Estimate:40000}, {Region:"Southwest", Territory:"Northern California", Territory_Rep:"T.R.

第二种 复杂表头
定制ClassFactory。。。重写展现方式
Code
