How do you create a report for Work Center Capacity Variation

I'm trying to create a report so that the maintenance team can see how many "variations" they have scheduled across multiple work centers.

the table CAPVAR is not at all structured like the grid in the work center page.  Does anyone have a report already created to help with this analysis or can help me even understand how to google my way into knowing how to report on this data with a table like that ?
