It's a real kludge, but you could also try creating 100 parameters and pass those
to the report. It's not the most eligant method I've ever seen but it might work if there's not a limit on how many parameters you can create. Of course, you'll still need to write some PL/SQL code in the report to parse out your columns.
Below you find some code where I create a parameter (the where clause of a select stmt) and pass it to a report.
Hope this helps if nothing else does.
