Sorry, I accidentally hit TAB+enter before finishing the writeup. ^^ Overview: Rules=none suppresses all internal table borders. This is contrary to CSS2, section 6.4.4, which specifies that CSS properties override HTML's presentational markup. Additionally, "rules=none" is the default behavior specified by HTML 4.01, and a table that does not have this attribute set should display the same as a table with "rules=none" explicitly set in the <TABLE> tag. CSS2:6.4.4 - http://www.w3.org/TR/REC-CSS2/cascade.html#q12 HTML4.01:11.3.1 - http://www.w3.org/TR/html4/struct/tables.html#adef-rules Steps to Reproduce: Open up testcase (to be attached shortly). Actual Results: Table 1, which has no attributes in the <TABLE> tag, renders the CSS border on Cell A correctly. Table 2, which has "rules=none" in the <TABLE> tag, does not display the border on Cell A. Expected Results: Both tables should display exactly the same. Tested with May 29th build (id=2000052908) on Windows 2000 ¬_¬

fantasai@escape.com could you make a comment how your bug report relates to bug 21076. Thanks Bernd

From looking at it just now, I thought I'd need to understand the underlying code to do that, but.. I ran another test on this and found that the "rules" attribute overrides any CSS border, no matter what its value. I think this might be the problem with the implementation of "rules" without a "border" in bug 21076 -- the rules attribute needs borders specified in order to display properly. However, that's besides the point: the rules attribute is overriding the CSS borders. I changed the summary and will attach a new testcase to demonstrate.

Confirming bug. Why isn't there a standardized attribute-mapping mechanism so the code doesn't have to get this right every time? Or is there?

We had always assummed that an explicit rules= overrides CSS, but maybe this is wrong. This bug has been marked "future" because we have determined that it is not critical for netscape 6.0. If you feel this is an error, or if it blocks your work in some way -- please attach your concern to the bug for reconsideration.

I figured out some style rules that might work. I realize that this probably won't actually be implemented CSS, but it might help as a suggestion. View source to see comments (within the style sheet). BTW, IE5 (Windows) handles "Table's Rules - HTML vs. CSS" correctly in all except the last table (with rules=groups).
