The web page at https://documentation.ubuntu.com/lxd/en/latest/reference/manpages/lxc/list/ has a broken layout compared to the output of lxc help list though they are clearly from the same source.

    D - disk usage
    e - Project name
    l - Last used date

    M - Memory usage (%)
    n - Name
    N - Number of Processes

    P - Profiles

@minaelee are you able to take a look at this one please?

Hi @minaelee is this still on your radar? Thanks

This is in the docs backlog (Jira ticket).

The man pages are converted from Go to Markdown. The origin uses single newlines, which are ignored in Markdown. Converting each single newline to a double newline in Markdown would cause the formatting in many other pages to break; using double newlines in Go would break the formatting in the CLI output. I will need to look further to resolve this.
