Many columns (as FK) vs 3x more Columns (in the same table)

Hi, i strugling to decide what is the best choice:

I have a 15 row x 3 columns Flash DataGrid, it means, for each row i have 3
values.
To represent this in my Database, I could:


   1. Create 2 Tables : A Values table - with 3 columns ; and a Bill table
   (with 15 foreign keys, each one pointing to one row in the Values table).
   2. Create one Table with 45 columns (15 fields * 3 values for each
   field).

I want to know, wich is the best choice?
To manage my query, now i have a SELECT with a thousand of leftJoins.

This is the best choice?

How could I run a query wich will give all results linked, like:
( column_1_val_1, column_1_val_2, column_1_val_2,
  column_2_val_1, column_1_val_2, column_1_val_3,
 etc...) ?

Thanks!
