 Sorting in the library should support the user sorting
across multiple columns. A sort from one display of a
table should be used as input for the sort on the next
column.

eg. From the initial table (warning: ugly ascii art follows)
Name | Dept | Role
=======================
Bob | Sales | Manager
Joe | Dev | Engineer
Fred | Dev | Manager

Sorting this by Name gives:
Name | Dept | Role
=======================
Bob | Sales | Manager
Fred | Dev | Manager
Joe | Dev | Engineer

Sorting this by Dept gives:
Name | Dept | Role
=======================
Fred | Dev | Manager
Joe | Dev | Engineer
Bob | Sales | Manager

Note that Fred now comes *before* Joe in the list.

Implementing this would mean that sorting would work in
the same way that it does in standard windows list
views, so would work the way many users would expect.

This would be a great feature. Something like multisort="country, state, city", would sort all three columns.

Of course a developer can add this with an external sort, but this makes it harder to be used by designer types.

The only inconvenient that I see is that you would not be able to change the multisort dinamically

Are there any plans to add secondary sorting to the displaytag library?

Workaround for secondary sorting with display tag:

If the list of objects is sorted from the backend, that sorting is retained while sorting on other columns.

Limitation of this workaround is that the secondary sort column is fixed.
