What is it?
The rendering of table borders is divided into two categories in CSS2 -
"collapsed" and "separated". This property specifies which border
rendering mode to use. In the collapsed border model, adjacent table
cells share borders. In the separated model, adjacent cells each have
their own distinct borders (the distance between them given by the
'border-spacing' property.)
In the CSS2 collapsed border model, provision is made for resolution
of cases where borders specified for adjacent cells differ and are in
conflict:
If any shared border has a component where the 'border' is set
to "hidden" for ANY of the sharing members, the common
border should be unconditionally set to "hidden".
If any shared border has a component where the 'border' is set
to "none", it can be overridden by any other border-sharing
member carrying a renderable 'border' property value. If ALL
border-sharing members specify a value of "none" for a border
component, only then will the border be set to "none".
If a shared border has a 'border-width' contention, (with no
component having a 'border' value of "hidden" of course...),
the largest border-width should be rendered.
If a shared border has a 'border-style' contention, the suggested
priority should be used (decreasing from left to right): "double",
"solid", "dashed", "dotted", "ridge", "outset", "groove", "inset."
If a shared border has a 'border-color' contention, the suggested
priority should be used (decreasing from left to right): Table cell,
table row, row group, column, column group, table.
