[css-tables] Missing definition of table row borders if border-collapse: separate?

I'm missing a definition in CSS about how table borders will be rendered if 
being applied to table-row elements, particularly in regard to the 
"border-collapse" property.

The following CSS doesn't seem to show borders, although that's supposed to 
be the only reason for the CSS property border-collapse:

I would suppose that given "border-collapse: separate" and "border-spacing" 
 > 0, a table row's border would be contiguous, not splitted across its table 
cells, like depicted in the attachment of this message, or found here:
