Mediawiki wikitable default sorting in descending order

Question

I have something like

{| class="wikitable sortable"
|-
! Year || Country
|-
| 2000 || US
|-
| 2001 || Japan
|-
| 1999 || Germanay
|}

But I want this will appear in wiki page automatically in descending order of year, even if I put 2000 before 2001.

Can I choose such "default" for wikitable ordering?

Answer 1

No.

But if you haven't disabled MediaWiki/Common.js, you could rearrange the table on pageload with JavaScript. See also https://meta.wikimedia.org/wiki/Help:Sorting#Default_order (“It is not possible to make a table appear sorted by a certain column without the user clicking on it.”)
