I'm not sure the problem is on `csv-mode.el`, tho.
I just tried it on a TSV file of mine where I can indeed see incorrect
alignment (tho it is correct both when displaying the leftmost columns
and when displaying the rightmost column: the errors show up only when
I scrolled in the middle for me).
But when I look with `C-u C-x =` at the TAB separator between two
columns, I see that two misaligned separators both show:
display (space :align-to 63)
and when I try `M-: (current-column)` I see that one of them says 60 and
the other says 61, so both elastic spaces *should* end at the same
column 63, AFAICT, even tho they clearly don't on my screen. Also, the
60 -vs- 61 is odd because the column position on screen of those two
positions differs by 3 rather than by 1, according to my eyes.
So, my crystal ball suggests the error might be in the redisplay.
Stefan
