We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, you may find it is not as difficult as you think!
If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!
But...I'll give you some clues.
Look at the data you want to generate:
1 2 3 4 5
2 4 6 8 10
3 6 9 12 15
4 8 12 16 20
5 10 15 20 25
First off, it's 5 rows of 5 columns: so you need two loops: one for the rows, and an inner one for each column.
Secondly, if you look at the actual data, the pattern is pretty obvious:
the cell value is the row times the column!
So the value you put in each cell is rowNumber * columnNumber (assuming numbering starts at 1 for each).
That's pretty much all you need to do!
So give it a try...
