在Flex中动态生成表格，并且表格的表头也是动态生成

1、源码

复制代码 代码如下:

<?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]

//自定义数据源

private var grid:Array = [

{age:'25', sex: "男",name: "张三"},

{age:'22', sex: "女",name: "李四"},

{age:'23', sex: "男",name: "王五"},

{age:'21', sex: "女",name: "赵六"},

{age:'24', sex: "男",name: "钱七"},

{age:'20', sex: "女",name: "魏八"}

];

/*初始化函数*/

private function initHandler():void

{

var gridArray:ArrayCollection = new ArrayCollection(grid);

gridArray.filterFunction;

//自定义DataGrid控件

var dataGrid:DataGrid = new DataGrid();

//X轴坐标

dataGrid.x = 20;

//Y轴坐标

dataGrid.y = 20;

//数据项是否能编辑

dataGrid.editable = false;

//控件宽度

dataGrid.width = 1300;

//控件高度

//dataGrid.height = 600;

//设置表格行数

dataGrid.rowCount = gridArray.length + 1;

//设置控件内容字体大小

dataGrid.setStyle("fontSize", 20);

//设置表头颜色

dataGrid.setStyle("headerColors",[0xB0C4DE,0xB0C4DE]);

//设置字体位置

dataGrid.setStyle("textAlign","center");

//设置样式名

dataGrid.styleName;

// 设置数据源

dataGrid.dataProvider = gridArray;

// 添加监听事件类型与触发函数

dataGrid.addEventListener(ListEvent.ITEM_CLICK, itemClickHandler);

// 添加dataGrid控件

addChild(dataGrid);

//声明一个数组

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);

}

</mx:Script>

</mx:Application>
