OK, but how about providing a USEFUL use case.
No one is going to use Column Editor to insert a single number.

Are you serious? This is a minimal example.

Hmm... I can reproduce with several lines:

@cddiffz
I can assign this issue to you if you want to provide a PR.
Otherwise, I'll fix it.

[cddiffz]

Please assign it to me.

Hmm... after playing around, here's the result:

The first column with "leading zero" and the 2nd column with "None".

So what I have said is not wrong:
#15152 (comment)

However, I believe that if Hex is selected, "leading zero" should be forced chosen. What do you guys think?

[cddiffz]

I would let the user decide and treat all number systems equally.

@cddiffz

I would let the user decide and treat all number systems equally.

In this case, what's the correct result of the 2nd column (with "None") for you?

[cddiffz]

aFE b
aFF b
a100b
…
a110b

[donho]

aFE b
aFF b
a100b
…
a110b

OK
