Consider removing table sorting model

[smaug----]

https://html.spec.whatwg.org/multipage/tables.html#table-sorting-model is complicated and at least Gecko nor Blink seem to have support for it.
I don't see any relevant properties in http://trac.webkit.org/browser/trunk/Source/WebCore/html/HTMLTableElement.idl either.

There are existing script libraries doing the sorting and scripts can be always more flexible deciding which way to sort.

I don't think anyone is working on this feature in WebKit. @hober

Yeah, I guess we should remove it. It is somewhat unfortunate though since it's a great feature.

👍 to remove

[hober]

Yeah. Sadface, but it's a good candidate for removal.

I don’t object to removing it but would have been happier to see a concrete proposal for simplifying it (though I’m not volunteering to write one). That said, it seems somewhat clear at this point that we’re not likely to ever get implementor support for this regardless of how it’s specced. I hope that’s not a failure on our part to align with the Priority of Constituencies in the way we should be (because I think this is something that we bring real benefits relatively directly to end users), but I guess users have been managing for all these years to get by without the Web having it, so it’s not like dropping it from the spec would be regressing anything. Still, sad.

As discussed above because it is not supported anymore. The Table sorting model in https://html.spec.whatwg.org/multipage/tables.html#table-sorting-model and one of it's example below it needs to be removed. There is one more example related to it https://html.spec.whatwg.org/multipage/semantics.html#dom-data-value this needs to be removed too.

Hmm. This might not be a good first bug. The table sorting model has a lot of parts that need to be removed, not just that section. For example, you'd probably need to merge HTMLTableHeaderCellElement and HTMLTableDataCellElement back into HTMLTableCellElement (since that's what's implemented everywhere), and remove everything to do with the "scope" property, and remove related examples that reference "table sorting model", and probably more I am forgetting...

Relevant commits that added stuff that should probably be removed:

• 6db0d8d
• f1b702f
• 427c247
• 2699e4a

plus probably more.

I don't think this is a good first bug... You're welcome to work on it still though!

Oh ok i'll see into it, and try to find other related examples too.
