Make sortDescFirst or "next sorting order" available on Column

[NixBiks]

AFAIK it's not possible to know what the sorting order will be on next click. It is being determined by

          const sortDescFirst =
            column.columnDef.sortDescFirst ??
            instance.options.sortDescFirst ??
            column.getAutoSortDir() === 'desc'

from here.

Use case

Show sorting order on hover, e.g. see this example

Current solution

Currently I simply mimick the above to determine the initial sort order for each column - it just feels a bit like hacking into the internals

Hey, @mr-bjerre! I guess your use case can be handled by using header.column.getIsSorted()

[NixBiks]

If that's false then you don't know if it will be ascending or descending next. That's determined by the code I put above AFAIK

This is not the behavior that I'm seeing when I use header.column.getToggleSortingHandler().

For me this is the current behavior when I click:

No sorting -> 'asc' -> 'desc' -> No sorting.

You can also see this in this example.

That way, getting the sorting order of the next click is possible.

Have you tried with both numbers and non-numbers columns? They have different defaults

[rodolphoasb]

Yeah, you're right with numbers the sort order is inversed...

Well, I guess you could convert all your data cells to strings. But IMO, I also feel like it's strange the starting sort order to be different according to the data type. Maybe open an issue?!

[NixBiks]

Well I did solve it properly - I'm just making this thread as a feature suggestion; I.e. to expose the "next sort order" on each column.

I like this idea and would use something like column.getNextSortingOrder() myself. Propose a PR?

I might give it a shot later this week
