You don't need to use third nested loop, your two nested loop is enough.
First, however, you need to think first, how you'd generate the output.
Following your thinking pattern, I'd do it like this:
#1
| 2 3 4 5
#2
| 2 3 4 5
==================
2 |
#3
| 2 3 4 5
==================
2 | 4
#4
| 2 3 4 5
==================
2 | 4 6
#5
| 2 3 4 5
==================
2 | 4 6 8
#6
| 2 3 4 5
==================
2 | 4 6 8 10
#7
| 2 3 4 5
==================
2 | 4 6 8 10
3 |
#8 etc
Do you see how you could generate the table headings?
