Sorting headed lists

[David Barnett]

Perhaps have a 'sorting' column sitting there. When a column header is clicked, grab the calculation for that column and use a $sendall (or similar) which calculates and puts the value into that sorting column for every line in the list. Then do the sort on that column. You never view this one. Just refill it each time the list is sorted.

These “display columns” can even include style() info for special formatting, etc. I don’t know of any way to access the “$contents” of a displayed column in a headed list comparable to the $contents of an entry field, so I think the pre-processing in parallel list columns is the best approach.
