This is still an issue.

See the patch in Bug#41852.  Perhaps the work regarding this can
continue there.

This is still an issue.

This seems to have been fixed since this bug was reported.

We now have the commands `{' (`tabulated-list-narrow-current-column')
and `}' (`tabulated-list-widen-current-column').  But it would be nice
to also have controls to change the widths using the mouse.  I guess the
challenge would be to ensure that it worked smoothly, as the mentioned
commands are fairly slow (average 0.4 seconds on my machine in
`list-packages').
