This is an alias to shells to display mount output in formatted columns.
Add this alias to your rc shell(.bashrc, .zshrc, or whatever):
alias mountc='mount | column -t | sort -V'
Example output:
$ mountc

You can also filter some outputs, like cgroup, /sys/:
alias mountc='mount | column -t | grep -v "type cgroup" | sort -V'
alias mountc='mount | column -t | grep -v "/sys/" | sort -V'
