@quantonganh I referenced your command in another post.
I had to replace the decimal separator in dockers {{.Size}} which seems to be always a dot, with the one of my locale to make sort -h work properly.
docker images --format '{{.Size}}\t{{.Repository}}:{{.Tag}}\t{{.ID}}' | sed 's/\./,/' | sort -hr | column -t
Note: the sed command blindly replaces the first "." per line.

Setting locale collate would do the trick as well. Something like this should work too:
docker images | LC_COLLATE=C.UTF-8 sort -k7 -hr
