[Bug 6319] New: Tables and border-separation

+++ This bug was initially created as a clone of Bug #6267 +++

+++ This is from the second half of Bug #6267. +++

Now about tables. Section 6.7.3, “fo:table” says that in the separate
border model the border of the table is composed of half the value of
the border-separation property plus the border as specified by the
property. Which would mean that the border-start(trait) would, in this
particular case, be different from the border-start(property):
    border-start(trait) = border-start(property) +
border-separation.inline-progression-dimension / 2

That’s why it seems important to me to know whether we are speaking of
traits or properties in the formulas above. If both formulas use the
same value (trait or property), then we have the result #1 on the
attached picture. If formula (1) uses the trait and formula (3) uses the
property, then the simplification will give:
    xa = start-indent + start-intrusion-adjustment
         − border-start(property) − padding-start
         − (start-indent − border-start(trait) −
padding-start)
       = start-intrusion-adjustment + border-separation.i-p-d / 2
Leading to result #2 in the attached picture, which is a sensible
result.

And if formula (1) uses the property and formula (3) the trait, we get
result #3 which is probably less likely to be expected.


Finally, Section 6.7.3, “fo:table” and Section 6.7.10, “fo:table-cell”
mention the “table grid boundary line”, but it is unclear where this
line should actually lie, especially with respect to the table padding.
There seems to be an inconsistency since Section 6.7.3 states that “the
first [border component], which is placed with the inside edge
coincident with the outermost table grid boundary line, has the width of
half the value for the ‘border-separation’ property”. And Section 6.7.10
states that “the first [border component], which is placed with the
outside edge coincident with the table grid boundary line, has the width
of half the value for the border-separation trait”. Then where shall the
padding be placed? The only consistent way to resolve this issue in my
opinion is to make the padding coincide with the table outermost grid
boundary line. See the attached picture as an illustration (where
case #1 from above has been selected). It might be helpful to add an
indication with this respect in the Recommendation.

Adding original poster as CC since response will be required when a solution is
proposed.
