When visiting http://www.whitver.net/~josh/calendar.html, the top row's text is
spilling across the table border, and the table cells themselves are too small.
 The right-most column would likely suffer the exact same too-small cell
problem, if it weren't for other text items in the row forcing the cells to be
tall enough.   The text is still too low, however.  See the attached JPEG.

Reproducible: Always

Steps to Reproduce:
1. Visit http://www.whitver.net/~josh/calendar.html (If you get no response, try
later; I upgraded the server's processor and it likes to overheat, requiring a
reboot).

Actual Results:  
Incorrectly-rendered schedule table.

Expected Results:  
Correctly-rendered table. :)

Josh, that HTML is nowhere near valid. What's all that "cool," "usegridx,"
"usegridy," "showgridx," and "showgridy" gibberish?

Remember, just because it looks the way you want in GoLive doesn't mean it's
going to work that way in a real web browser.

Try running it your page through validator.w3.org. Fix those problems, then
let's see if there's a Mozilla bug here.

Resolving Invalid for now. Reopen when you have a better testcase, please. Thanks.

While it may not be the world's best HTML, the official 0.7 release renders
it fine, as does every other browser I've tried it with.  It only started
rendering incorrectly when I downloaded a nightly Camino build newer than the 0.7
release.  To me, that pretty strongly implies a Camino bug of some kind
(whether it's Camino specifically or something with the Mozilla 1.3 engine,
I don't know).

Okay; I've put up a new page at http://www.whitver.net/~josh/tabletest.html
that's free of all the evil GoLive stuff (which I've also posted as an
attachment).  The problem still occurs.  I'll reopen the bug, if that's okay. :)

The issue is related to the page's css rule (height: 0px) which is applied to
the H4 element. I have a reduced test case showing this problem.

Comment 7

[Chris Petersen]

No longer just a camino issue since this reproduces in the latest mozilla trunk
build.

changing to layout:tables

Attachment: reduced test case

Test case contains a table with a nested P element. The P elemennt has been
assigned { padding: 1px; height: 0px } ccs rule.

Changing bug URL since I've since updated the calendaring system on my website. :)

I think the p should not wrap around the text so for me mozillas rendering is correct

Comment 12

Attachment: strict mode

this is partly a quirks mode question
webkit and FF3 honor the style height on the P in std and quirks mode
IE honors the style height only in std mode
Opera is completely off with their standards mode rendering
