Create a column summary with drill-through to filtered data

Given a basic table T with N columns.

I'd like to take a subset of columns from T and transpose them to rows.

Then compute a summary value for each of these rows, and then drill-through to

filter a table on a second page...the summary table would look like this:

colname | summary

-------------------------

abc         |  value1

def         |  value2

ghi         |  value3

Is this possible?

I tried using the ROW function to manually build rows, but the column

names are just strings -- they don't link back to data.

I also tried using the ROW function to manually build a table, but could

not make the drill-through work from inside a ROW structure...

Thanks!
