For sed, I would suggest the following, which is resilient to trailing spaces in the first field:

No. It will remove trailing spaces (if present) only in the second field. The first field will always match, since the spaces are optional (there is only one space in my regular expression). The second match will always be the second field.

I believe you omitted a * quantifier, otherwise your re will only match a second field with a single non-blank followed by blanks. But including the * could lead to a problem with greediness spilling over into subsequent fields if the second field has no blanks. The first [^<spc><tab>] should be [^|]. Regardless, it will fail to remove trailing blanks if there is an embedded blank.
If trailing spaces in the second field need to be deleted, I believe my suggestion is both accurate and robust.
