Why? Both of those structures are probably incorrect. When you start numerating field names, you need to reevaluate your tables.
That data should probably be stored as such:
run_name, sample_name, Fvalue, Fnumber
1, sample1, 62115, 1
1, sample1, 113875, 2
1, sample1, 195050, 3
That is assuming the number after 'F' in your field names is actually needed.
