当我删除打印重复值

Branch  ID  date    tax total
banglore    bang01  22-11-2013  450 5000
            350 4300
            450 5000
    bang02      350 4300
            250 2500
    bang03  24-11-2013  350 4500

但我想要这样：

Branch  ID  date    tax total

            350 4300

bangalore   bang02  22-11-2013  350 4300
            250 2500
banglore    bang03  24-11-2013  350 4500
