用jxl将多个excel文件合并成一个多sheet的excel文件

private static void beginMergerColumn(){
   try {
       InputStream fis1 = new FileInputStream("D:/合并文件/4/营业务汇总表.xls");
       InputStream fis2 = new FileInputStream("D:/合并文件/4/产权抵押融资汇总表.xls");
       Workbook wb1 = Workbook.getWorkbook(fis1);
       Workbook wb2 = Workbook.getWorkbook(fis2);
       WritableWorkbook newWb = Workbook.createWorkbook(new File("D:/合并文件/4/jxl_6.xls"));
       newWb.importSheet("NewSheet0", 0, wb1.getSheet(0));
       newWb.importSheet("NewSheet1", 1, wb2.getSheet(0));
       fis1.close();
       fis2.close();
       wb1.close();
       wb2.close();
       newWb.write();
       newWb.close();
   } catch (BiffException e) {
       e.printStackTrace();
   } catch (IOException e) {
       e.printStackTrace();
   } catch (WriteException e) {
       e.printStackTrace();
   }

}

jxl.jar  一定要注意使用的版本
