jxl处理excel文件

haha先留下以后几不用搜索了。        

之前都没有用java去操作过excel，项目需要，所以专门去了解了下，看到有用到jxl这个插件，感觉很实用。特地建个备忘录，以便以后自己查询:
public static void main(String[] args) {
  try {
      Workbook wb=Workbook.getWorkbook(new File("e:\\test.xls"));
      Sheet sheet=wb.getSheet(0);
      Cell[] cellcol=sheet.getColumn(0);
      for (int j=0;j<cellcol.length;j++) {      ①
       if(cellcol[j].getContents().equals("测试酒店1")){
Cell[] cell=sheet.getRow(j);
for(int i=0;i<cell.length;i++){
    System.out.println(i+":"+cell[i].getContents());
}
        }
       }
      wb.close();
  } catch (BiffException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
   } catch (IOException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
   }
}
① 因为头回接触 ， 不知道怎么获取特定行里头的数据，所以用了个很原始的方法，先获取某一特定列的值，然后匹配你所特定的，然后获取那行数据
