ZK grid or list数据多列排序

//按grpID,priority從小到大排序      Comparator TotalOrderMoneyComparator = new Comparator() {         public int compare(Object o1, Object o2) {PdbMcmCpnoDO co1 = (PdbMcmCpnoDO) o2;PdbMcmCpnoDO co2 = (PdbMcmCpnoDO) o1;int flg = -1;flg = co1.getGrpId().compareTo(co2.getGrpId());if (flg == 0) {flg = co1.getPriority().compareTo(co2.getPriority());}return flg;}};CompoundComparator cc = new CompoundComparator();// 添加比较器cc.addComparator(TotalOrderMoneyComparator, false);// 实现排序Collections.sort(allCpnoDOs, cc);
