Section 10.2.6, i.e. The XHTML syntax: Rendering: Punctuation and decoration
contains some style rules for handling the [rules] and [frames] attributes
of the <table> element. I haven't reviewed it all in detail but this part
table[frames=void] > tr > td, table[frames=void] > tr > th,
table[frames=above] > tr > td, table[frames=above] > tr > th,
table[frames=below] > tr > td, table[frames=below] > tr > th,
...
table[frames=border] > tfoot > tr > td, table[frames=border] > tfoot > tr >
th {
border-style: solid;
}
is certainly wrong both per spec (HTML4) and implementation. It should be
removed. Also, you probably want to track Mozilla bug 43178 for this section
https://bugzilla.mozilla.org/show_bug.cgi?id=43178
since we are actually planning to implement these attributes with CSS rules
unless we hit performance problems with that approach.
There's a collection of tests for these attributes here:
http://fantasai.inkedblade.net/markup/tests/table-frame-rules/
I should probably expand it to include tests for the empty string and junk
valuse, but that's what it is for now.
