At present, there is nothing you can do to sepate the "native range"
values because SMW forms the comma separated list before passing it to
the Template.
What we really need is the ability to have multiple templates being
used. That way the template= parameter would give a list of templates.
The first template would be used as now, and the second and subsequent
templates would be used to format the values from each column.
So:
-----Some Page-----
[[reference A::page X]]
[[reference A::page Y]]
[[attribute B:=value P]]
[[attribute B:=value Q]]
-----Other page----
<!-- NB no template given for column 1 -->
<ask format=template template="main template;;col 2 template;col 3 template">
[[reference A::+]][[reference A::*]]
[[attribute B:=+]][[attribute B:=*]]
</ask>
----main template----
|-
| {{{1}}}
| {{{2}}}
| {{{3}}}
----col 2 template----
{{#if:{{{1|}}}|<nowiki/>
* [[{{{1}}}]]}}{{#if:{{{2|}}}|<nowiki/>
* [[{{{2}}}]]}}{{#if:{{{3|}}}|<nowiki/>
* [[{{{3}}}]]}}{{#if:{{{4|}}}|<nowiki/>
* [[{{{4}}}]]}}{{#if:{{{5|}}}|<nowiki/>
* [[{{{5}}}]]}}
----col 3 template----
{{#if:{{{1|}}}|<nowiki/>
* {{{1}}}}}{{#if:{{{2|}}}|<nowiki/>
* {{{2}}}}}{{#if:{{{3|}}}|<nowiki/>
* {{{3}}}}}{{#if:{{{4|}}}|<nowiki/>
* {{{4}}}}}{{#if:{{{5|}}}|<nowiki/>
* {{{5}}}}}
The above would produce tabular layout with the items in the 2nd and
3rd columns being bulleted lists rather than comma separated.
Lets hope something like this arrives in the next version of SMW.
On a similar note it might be useful if we had headertemplate= and
footertemplate= parameters for ask, which are only used when there is
something to display.
