You need a bit more explanation.....

i mean how to arrange the "name" and "class" in the first table into the second table that fits to the "code"

In B10

=VLOOKUP($A10,$A$1:$C$5,COLUMN(B$1),False)

and copy down and across. But your example does not have the same values, so some cells may be errors.

thank you man but i dont know why some values are different, this is the excercise the recruiter asked me in the interview and i couldnt resolve it
