[css-tables-3] Unclear definition of offset-adjusted cell measures

[Manishearth]

https://drafts.csswg.org/css-tables/#offsets-adjusted-width

offsets-adjusted min-width, width, and max-width

• For table-cell boxes, the offsets-adjusted value of width properties is their computed value from which the cell’s border-{left|right}-width and/or padding-{left|right} have eventually been deduced, depending on the value of box-sizing.

Should this say "deducted"? I'm not sure how I'm supposed to deduce anything. Some more explicit text would be nice, like "if box-sizing is border-box, this is min-width - border-lr - padding-lr"

Also, are the values deducted the ones from https://drafts.csswg.org/css-tables/#cell-intrinsic-offsets ?

It would be nice if all these things used cross-references 😄

[Manishearth]

Similarly, in https://drafts.csswg.org/css-tables/#outer-min-content, when it says "adjusted by the cell intrinsic offsets", is it just saying the "The width, min-width, and max-width values used in these definitions are the offsets-adjusted values defined above: " part again?

[Manishearth]

The outer min-content width of a table-cell is max(min-width, min-content width) adjusted by the cell intrinsic offsets.

Actually, is the adjustment here addition because it's outer?

I.e. does this expand to

let adjusted_min_width = min_width - (is_border_box?(paddinglr+borderlr):paddinglr);
let outer_min_content = max(adjusted_min_width, min_content_width) + paddinglr + borderlr;

This makes the most sense to me. I'd be happy to make a PR if you can confirm that this is indeed the case.

Also, what should be done if these values contain percentages?

Yes, it should, deduce is a typo ;)

Yes, a cross-reference could be added indeed.

The outer min-content width of a table-cell is max(min-width, min-content width) adjusted by the cell intrinsic offsets.

This is how I interpret this indeed.

Borders can thankfully not be percentages.
This leaves the question of padding. I'd assume things would work the same as for percentages elsewhere for tables:

• During first pass, ignored as auto (here means 0px)
• Then when the distribution has happened and cells have their final sizes, padding is accounted for in the final layout, possibly causing the content of the cells to overflow.

https://wptest.center/#/nm1qw4 written with this assumption passes in both chromium and gecko

Now, where do we want to specify this behavior explicitly in the text? in the definition of cell intrinsic offset for the part about considering percentages as 0, and then one more note somewhere to mention the values are used when doing final cell layout?
