Yes, cells in columns go right to left when direction is rtl. That
doesn't mean padding-left means right padding!

Why not? direction: rtl make cells go right to left just the same as
dir=rtl.

The only reason to use dir=rtl instead of direction would be something
like Korpela's CSS Kaveats.

I agree. I think this "belongs" in HTML rather than in CSS. But since
they need to specify various things about how things are laid out it
needs a CSS property for consistency and to save cross-referencing the
HTML specs.

The only place the direction property should probably normally be used
is in the browser default stylesheet.

Updated version with direction:rtl .

I have not yet seen the updated version of my test page in Opera
but I would be even more surprised if there is a difference between
dir=rtl and direction: rtl .

On Mac Opera 10.10, there is no difference between your rtl and
ltr tables showing up. Once again, the "bug" that is being found
here is dependant on you specifying right-padding in em rather
than other units. Continue to find this uninteresting.

I see - when I write { padding-right: 50mm }, I get the padding
on the right side. Strange, strange, strange

Yes, because I continue to specify length only in relative units.
