Removing padding within labels in profile type matrix tables

Hi all - I am looking to remove the padding for all scale labels within a profile type matrix table. Basically, I want to uniformly, vertically top-align all the text across the scale points. As you can see below, it looks like I have achieved it for some rows (the first "Shared Vision") but not for others (the second, "Goal Setting and Strategic Planning"). I think I have identified the problem--a padding issue in the label, but I cannot figure out how to change it with just the "element.style" selector option. I have tried putting this CSS into each label itself using the Rich Content Editor, with no luck.
Any ideas?
