How do I remove a gap between table rows in InDesign?

Question

I need help in figuring out how to remove gaps between table rows.  I have tried Table Spacing under Table Set-up, but it doesn't work.
Here's what I'm working on:
As you can see there are gaps above the first row and below last row under the header Business Management Technology.  I cannot select that gap.  How do I remove it, so that the first class, 31058, is flush with the black header?  (and the last class, 32675, is flush with the Chemistry header?)
Any advice would be greatly appreciated.
Thanks,
Sarah

I hadn't considered that, and your example is proof-of-concept. However, now that you made me look closer, I still don't think that's the OP's case, seeing as the text in the OP's header rows appears to span more than one column, belying what I suppose must be merged cells.* The column strokes in the "gap" appear to disqualify it (the gap) as part of a row with merged cells.
*There is still another possibility that someone "made pictures" of tables with merged cells by overlaying text frames to make the header rows. I've run across all kinds of such "carpentry;" especially when the file may have originated at the desk of someone who avoids or resists use of tables. They find ways to fake them and/or their features.
