扩展cell标签，增加两个属性currentcelltoColName和usecurrentCellValuetoCellName，使用方法如下：
<%
List rooms = new ArrayList();
for (int i =0 ; i < 10; i ++) {
Map map=new HashMap();
map.put("rommType", "麻将室"+i);
map.put("rommTypeID", "mj"+i);
map.put("overNum", (100+i)+"");
for (int j = 0; j < 10 ; j ++) {//设置动态属性

	map.put("day "+j+"剩余房间数:", (10+j)+"");//map增加时间段内的数据
}
rooms.add(map);
}
List<String> days=new ArrayList<String>();
for (int j = 0; j < 10 ; j ++) {
	days.add("day "+j+"剩余房间数:");
}
request.setAttribute("rooms", rooms);
request.setAttribute("days", days);

List<RoomDay> roomDays=new ArrayList<RoomDay>();
for (int j = 0; j < 10 ; j ++) {
	RoomDay roomDay = new RoomDay();
	roomDay.setDay("day "+j+"剩余房间数:");
	roomDays.add(roomDay);
}
request.setAttribute("rooms", rooms);
request.setAttribute("days", days);
request.setAttribute("roomDays", roomDays);
