Which approach is better?

[weitat chok]

hi, i hv a situation, a table called campaigns, and each campaign may hv diff setting, or with default setting
let say, i hv 5 setting, s1, s2, s3, s4, s5, where s1 to s5 mayb string or any possible integer

Note: not every camp need those setting, some may hv s1...s5 to NULL

there should be two approach for the table

Case 1:
table A
camp_id, camp_name, s1, s2, s3, s4, s5

Case 2:
table A
camp_id, camp_name

table s1
id, camp_id, s1
table s2
id, camp_id, s2
table s3
id, camp_id, s3
table s4
id, camp_id, s4
table s5
id, camp_id, s5

then come back, i wonder which one should be best approach.
Coz once the sys running, i mayb come accross a case to check whether camp_id=5 hv setting s3 or not, to continue the script operation

Can some one tell me which would be system and programming viser?
