我想在jscrollpane中将jpanel排列为2列到容器

Question

我想在jscrollpane中将jpanel用于2个colums到容器。 我的来源

tree.addTreeSelectionListener(new TreeSelectionListener() {

        @Override
        public void valueChanged(TreeSelectionEvent e) {
            // TODO Auto-generated method stub
            TreePath path = e.getPath();
            Object lastPathComponent = path.getLastPathComponent();
            switch (lastPathComponent.toString()) {
            case "전체보기":
                ViewArr.clear();
                cont.removeAll();
                for (int i = 0; i < candy.size(); i++) {
                    cont.add(vi.CreateViewer(candy.get(i)));
                    jsp2.getViewport().setView(cont);
                }
                break;
            }
            /** 동적생성된 날짜별 노드에 대한 액션 */
            for (int i = 0; i < date.size(); i++) {
                if (lastPathComponent.toString().equals(date.get(i))) {
                    ViewArr.clear();
                    cont.removeAll();
                    for (int j = 0; j < candy.size(); j++) {
                        if (candy.get(j).getInterviewDate().toString()
                                .substring(0, 7).equals(date.get(i))) {
                            cont.add(vi.CreateViewer(candy.get(j)));
                        }
                    }
                    jsp2.getViewport().setView(cont);
                }
            }
        }
    });

容器是gridlayout（0,2,10,10）.. 我的来源的jpanel侧身成长.... 请帮我！请教我 最后，很抱歉让你看到有问题的写作。
