Usage

Set the border in the @Table annotation:

@Command
@Table(fields = "name version status", border = Border.githubMarkdown)
public List<Package> list() {
    return packageService.findAll();
}

Or override at runtime with the --table-border flag:

myapp list --table-border=unicodeSingle

For data interchange, tsv and csv produce plain delimited output suitable for piping into other tools:

myapp list --table-border=csv > packages.csv
