Select cols where null, based on other col's classification AvB?

Trying to brainstorm this. I have a big data set with a grouping col A vs B, then hundreds of data feature cols. One problem is that some of the cols only have data for one group or the other and thus aren't useful, so I want to select and exclude those cols.

 

How would I script: search group of cols when all rows = null for any of the groups
