I think of the single tab output by du, as providing
standard separation, with very rough alignment.
One can then adjust alignment easily outside of of du.
For example:
$ du -h | expand
20K My layouts/linda-default.fcl
20K My layouts/new-default.fcl
0 My layouts/foo.fcl
Or more sophisticated right alignment and number processing with:
$ du -B1 *.patch | numfmt --format=%6.1f --to=iec
20.0K My layouts/linda-default.fcl
20.0K My layouts/new-default.fcl
0.0 My layouts/foo.fcl
