[AstroPy] issue with initialisation of a fits binary table

I have a question about io.fits
I wonder if I just miss something obvious, or it can only be done as a
later fix. Let me explain my problem.
When adding a card to the header, I can do that as
header["NEW_KEY"]=("SOME_VALUE","this is an example")
and in the header I get
NEW_KEY = "SOME_VALUE" \ this is an example
So with a keyword.
Now, when I define a new column like
col = [fits.Column(name="Vmag",format="E",unit="mag",ascii=False)]
I can create a binary table
tab = fits.BinTableHDU.from_columns(columns=col)
The header then is created with a TTYPE keyword with a value, but without a
Comments are sometimes very useful, and so I checked.
I can define
col = [fits.Column(name=("Vmag","some
which goes some way to being able to have a TTYPE keyword with value and
but then trying to create the binary table HDU as before, it fails.
Am I missing something?
I can probably go back in and modify the header to add comments once I have
the bintable HDU defined, but it seems so inelegant I did not even try.
