Thanks. That's what I've done for now, until I figure out how to make 
CTools work. Frustratingly, the field has an ID, but neither the label, 
the cell they're in or the row that the cell is in have ID's. So without 
doing more work than is warranted, the field disappears but not its 
label. So when the field disappears, I replace it with a string 'Not 
applicable.'
