How to create edit delete dynamic table in asp.net - c#

i am using VS 2008 (asp.net with c#) and SQL Server 2005....

subject table: 

create table subject

(subid varchar(10),

subname varchar(20))

subid        subname

1               subject1

2               subject2

3               subject3

=> it includes all the subjects in each row...for eg

result table: it includes all subject marks ( when i'm trying to create result it repeating each row with subid,subname)

studentid     subid        subname             marks

1                   1              subject1                12

1                   2              subject2                23

1                   3              subject3                22

1                   4              subject4                20

here, it displays subjects and marks in row wise...

so i want something like this....

studentid     subject1    subject2    subject3    subject4

1                   12              23              22               20

2

3

so i want to display each subjects with its marks in column wise.....

NOTE:

Subjects are not fixed for each semester (in subject table) thats why i want to create/edit/delete table dynamically within asp.net web form....
