I get the extra whitespace between row 1 and 2 and between 3 and 4, but not between 2 and 3. Why?
[l][][l]are not legal arguments for \parbox and are being ignored. The first optional argument should bet,corb. The second should be the height, and the third should bet,c,bors. BTW, you could add vertical space to the parbox by specifying the height and using [t] for the third argument. – John Kormylo Sep 09 '21 at 13:57\sfhas not been defined by default in latex for almost 30 years,articleclass defines it for compatibility with latex2.09 documents – David Carlisle Sep 09 '21 at 14:02
