but can be resolved when the borders were drawn differently. I
believe (not sure) that the borders for each individual cell are
drawn as separate lines (or something), and not merged together as
lines that continue where they can (I believe this is the infamous
"collapse" issue?).
To be entirely complete: the borders are indeed drawn/rendered as
separate lines ('paths' is the corresponding term in PDF, IIC), but
strictly speaking, this is unrelated to border-collapse. IIC, and we
were to offer a basic implementation for border-collapse="collapse",
then this would not change the way the borders are rendered in PDF.
It would, OTOH, also be possible to draw borders as continuous lines
when border-collapse="separate" and border-separation="0pt".
You can compare the rendering of the borderstyle of the whole
table, and the borders of individual cells. I know it is not
possible to set borders for columns and rows yet, but if you could,
that would, by large, solve the problem without having to resolve
to "collapse".
Slight correction: to specify borders on columns and/or rows, one
precisely /does/ need the collapsing border model.
With border-collapse="separate", the only elements to which any
border properties apply are fo:table and fo:table-cell.
The issue by itself (short lines etc) is something I have seen
appear by most PDF creators I know off.
For as far as I can estimate it, it would be possible, but not at all
a trivial task to change the way the borders are rendered (from a
whole bunch of separate 'paths' or 'strokes' to a complete grid in
one piece).
Cheers,
Andreas
