Sorting headed lists

[Jean Marc Azerad]

Hi $all,

It's late and my brain is somewhere ... but can't find it... Maybe its obvious, maybe not...

When clicking on the header, I need to sort a headed list depending on the CONTENT of the displayed column, not the underlying list variable...
The content is dynamically calculated line per line and quite complex (include pick() con()..., so choosing fields in the list is just not possible.
Any clue anyone?

Thanks!
