It would be great if it were possible to support multi-row table headers in the table plugin, so you could do e.g.

    [[!table  header="""
    Name | Platform ||
    | Windows | Mac | Linux
    """ data="""
    ikiwiki | ‧ | ✓ | ✓
    """]]

-- Jon

This seems like weird overloading of the header parameter - it's table data, except when it isn't.

My first cut (now rebased out of existence I think) introduced a new "headerblock" parameter, but trying to clearly document the interaction of data/headerblock/header parameters was too awkward. -- Jon

Perhaps something like this would be easier to use in practice? (and also more featureful :-) )

[[!table  header="2 rows 1 column" data="""
Name | Platform ||
| Windows | Mac | Linux
ikiwiki | no | yes | yes
Starcraft | yes | yes | via Wine
"""]]

Thanks for your prompt feedback!

This would probably be good, yes, and having mixed row/column headers is definitely a nice-to-have. I don't relish the prospect of writing the parser but I see you've made a stab already...

One thing you'd lose, but it's debatable whether this is valuable, would be to have the header defined in the directive, and the remaining table data declared in an external CSV. -- Jon

intended to be rendered like

(Deliberately switching to plain-text to make it more obvious what's a <th> and what's <td>.)

Vague pseudocode for parsing headers (possibly even valid Perl, I'm not sure):

my ($header_rows, $header_cols);
while ($header =~ s/(\d*)\W*(\w+)//) {
    my $n = ($1 or 0);
    my $what = $2;
    if ($what =~ m/rows?/) {
        $header_rows = $n;
    }
    elif ($what =~ m/col(?:umn)?s?/) {
        $header_cols = $n;
    }
}

and it would even be fairly easy to extend to support (first|last|)\W*(\d*)\W*(\w+) later, e.g. header="1 row, first 2 cols, last column".

To be clear I think your suggestion is a good one, but my hack has addressed my immediate need so it's the one I'm deploying at $ork for the time being. I'm unlikely to have time to implement this solution in the near future. -- Jon
