单元格是可以拖动的，并且可以在三个List之间拖动，不过没加自动滚动来着。AS相当简单，三个List组件分别是list

1、list

2、list3，然后把所有代码copy到第一帧就可以了。

import fl.events.ListEvent;

import fl.controls.List;

import fl.controls.listClasses.ICellRenderer;

import fl.controls.listClasses.ListData;

//为组件添加数据

var i:uint = 0;

for(i = 0;i<21;i++){

list1.addItem({label:"label" + i});

}

for(i = 21;i<41;i++){

list2.addItem({label:"label" + i});

}

for(i = 41;i<61;i++){

list3.addItem({label:"label" + i});

}

//添加侦听器

list1.addEventListener(ListEvent.ITEM_ROLL_OVER,itemRollOverHandler);

list2.addEventListener(ListEvent.ITEM_ROLL_OVER,itemRollOverHandler);

list3.addEventListener(ListEvent.ITEM_ROLL_OVER,itemRollOverHandler);

list1.addEventListener(ListEvent.ITEM_ROLL_OUT,itemRollOutHandler);

list2.addEventListener(ListEvent.ITEM_ROLL_OUT,itemRollOutHandler);

list3.addEventListener(ListEvent.ITEM_ROLL_OUT,itemRollOutHandler);

stage.addEventListener(MouseEvent.MOUSE_DOWN,mouseDownHandler);

stage.addEventListener(MouseEvent.MOUSE_UP,mouseUpHandler);

//标记的组件和相应的行

}

}

//判断,是加到新组件中还是原组件中
