Dynamic Report Columns

[PWise]

Can columns in reports be set via code?
I have this report that I would like that it should be printed in this manner

1)Up to 50 records 1 column in the center of the page
2)51 to 100 more records 2 balanced column
3)101 to 150 records 2 balanced columns a 1 column in the center of the page.... and so on

Is there any way to set this up in code short of creating many reports?

Thanks for any help
