Question

我有一个显示mysql表中数据的php表。

现在该表已按部门的字母顺序排列，但每个部门内的用户不是。

在下面的示例中，您将看到部门按字母顺序排列，但每个部门下的用户数据不是。例如

                           Admin Department 
                Wade        3234234     Wade@acasdaas.com
                George      3434323     George@aasdsasas.com
                          Workshop Department
                Zyiad     45454523    Zyiad@aasdasd.com
                Buffy     48282191    buffy@assad.com
