效果如图所示:

测试sql语句如下:
复制代码 代码如下:
declare @tab table(Class varchar(20),Student varchar(20),Course varchar(50),Quantity decimal(7,2));
insert into @tab(Class,Student,Course,Quantity) values('A班','张三','语文',60);
insert into @tab(Class,Student,Course,Quantity) values('A班','张三','数学',70);
insert into @tab(Class,Student,Course,Quantity) values('A班','张三','英语',80);
insert into @tab(Class,Student,Course,Quantity) values('A班','李四','语文',30);
insert into @tab(Class,Student,Course,Quantity) values('A班','李四','数学',40);
insert into @tab(Class,Student,Course,Quantity) values('A班','李四','英语',50);

insert into @tab(Class,Student,Course,Quantity) values('B班','王五','语文',65);
insert into @tab(Class,Student,Course,Quantity) values('B班','王五','数学',75);
insert into @tab(Class,Student,【来源：美国cn2服务器 转载请说明出处】Course,Quantity) values('B班','王五','英语',85);
insert into @tab(Class,Student,Course,Quantity) values('B班','赵六','语文',35);
