flex dataGrid 中的editable问题 （急，急，急）
<?xml version="1.0" encoding="utf-8"?>

var checkBox:CheckBox = event.target as CheckBox;
if (checkBox != null) {
record.selected = checkBox.selected;
}
}

</mx:Script>
<mx:DataGrid id="adGrid"
width="300"
height="253"
fontSize="14"
dataProvider="{dataSource}"
x="262.5"
y="203"
editable="true">
<mx:columns>
<mx:DataGridColumn headerText="序号"
dataField="id"/>
<mx:DataGridColumn headerText="名称"
dataField="name" editable="true"/>
<mx:DataGridColumn headerText="年龄"
dataField="age" editable="true"/>
<mx:DataGridColumn headerText="是否选择"
dataField="selected"
textAlign="center"
editable="false">
<mx:itemRenderer>
<mx:Component>
<mx:HBox verticalAlign="middle" horizontalAlign="center">
<mx:CheckBox label="是" visible="{data.visible}"
selected="{data.selected}"
click="outerDocument.checkBoxClickHandler(event, data)"/>
</mx:HBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>
</mx:Application>
代码如上 ：怎么实现第一行和第五行不可编辑，其他行科技编辑，谢谢.
[解决办法]
监听表格itemEditBeginHandler事件，不满足条件的终止event.stopImmediatePropagation();
这样就达到了不可编辑的效果。
