Flex中動态生成DataGrid以及動态生成表頭

在Flex中動态生成表格，并且表格的表頭也是動态生成

1、源碼

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" 
				creationComplete="initHandler()"
				width="100%" height="100%">
	<mx:Script>
		<![CDATA[
			import mx.events.FlexEvent;
			import mx.events.ListEvent;
			import mx.controls.ComboBox;
			import mx.controls.DataGrid;
			import mx.collections.ArrayCollection;
			import mx.controls.dataGridClasses.DataGridColumn;
			
			[Bindable]
			//自定義資料源   
			private var grid:Array = [
				{age:'25', sex: "男",name: "張三"},
				{age:'22', sex: "女",name: "李四"},
				{age:'23', sex: "男",name: "王五"},
				{age:'21', sex: "女",name: "趙六"},
				{age:'24', sex: "男",name: "錢七"},
				{age:'20', sex: "女",name: "魏八"}
			];
			
			/*初始化函數*/
			private function initHandler():void
			{
				var gridArray:ArrayCollection = new ArrayCollection(grid);
				
				gridArray.filterFunction;
				//自定義DataGrid控件
				var dataGrid:DataGrid = new DataGrid();
				//X軸坐标
				dataGrid.x = 20; 
				//Y軸坐标
				dataGrid.y = 20;	
				//資料項是否能編輯
				dataGrid.editable = false; 
				//控件寬度
				dataGrid.width  = 1300; 
				//控件高度
				//dataGrid.height = 600; 
				//設定表格行數
				dataGrid.rowCount = gridArray.length + 1;
				//設定控件内容字型大小
				dataGrid.setStyle("fontSize", 20);
				//設定表頭顔色
				dataGrid.setStyle("headerColors",[0xB0C4DE,0xB0C4DE]);
				//設定字型位置
				dataGrid.setStyle("textAlign","center");
				//設定樣式名
				dataGrid.styleName;
				// 設定資料源
				dataGrid.dataProvider = gridArray; 
				// 添加監聽事件類型與觸發函數
				dataGrid.addEventListener(ListEvent.ITEM_CLICK, itemClickHandler); 
				// 添加dataGrid控件
				addChild(dataGrid); 
				//聲明一個數組
				var columns:Array = new Array();
				var column:DataGridColumn;
				for ( var i:* in grid[0] ) {
					column = new DataGridColumn(i);
					columns.push(column);
				}
				dataGrid.columns = columns;
				
			}
			
			/*事件*/
			private function itemClickHandler(event:ListEvent):void
			{
				trace(event.target);
			}
