使用jxl动态合并单元格

public List exportExcel(Domain domain, Finder finder) throws Exception {

SqlSession sqlSession = null;
try {
sqlSession = getSqlSessionFactory(domain).openSession();
KpDao dao = sqlSession.getMapper(KpDao.class);
List<Map<String, Object>> res = dao.findCriterion(finder);
this.queryCriterionAttr(dao, res);
System.out.println(res.size());
if (res != null && res.size() > 0) {
String author = res.get(0).get("author").toString();
// 1:创建excel文件
String filePath = "E:/test.xls";
File file = new File(filePath);
file.createNewFile();
// 2:创建工作簿
WritableWorkbook workbook = Workbook.createWorkbook(file);
// 3:创建sheet,设置第二三四..个sheet，依次类推即可
WritableSheet sheet = workbook.createSheet(author, 0);
// 合并单元格
sheet.mergeCells(0, 0, 3, 0);
sheet.mergeCells(0, 1, 0, 2); <
