From Bugzilla Helper:

Trying to align a table in the middle and center of a window.
<table style="width: 100%; height: 100%">
<tr valign="middle"> <td align="center">
...content of nested table...

the table centers itself but appears online after what seems to be equivalent to
2 line breaks instead of being in the middle of the page (vertical-wise).

then something even more strange is happening when two lines of text are parsed
before even the <!doctype> definition (which makes the page non-valid to the
rules): the table appears correctly.

Opera 5 and MSIE 5.5 are showing the page correctly

see for first case for second case

Reproducible: Always
Steps to Reproduce:
1. for first case
2. for second case

Actual Results:  
1. table does not align in the middle
2. table aligns in the middle but method is not w3-valid 

Expected Results:
should render like in Opera 5 / MSIE 5 windows.

Actually the valign="top" doesn't work at all no matter where it is tr or td. 
This is not following the w3c specification.  Gecko broken maybe?

Figured out what is happening.
If you put &lt;p&gt;&lt;/p&gt; around the text inside the table cell then it
causes a line feed prior to the text which can look sort of like the valign tag
isn't working, but it is, it's just the &lt;p&gt; tag causing the extra line break.
Leaving out the &lt;p&gt; tags avoids the problem.  This is not the correct way
to handle the paragraph tag.  The paragraph tag should only cause a paragraph
break if the previous tag is a tag that is on the same level in the hierarchy.
Say for example:
<p>Blah blah blah</p>
<p>And more blah blah</p>

First &lt;p&gt; has no paragraph break first, whereas second &lt;p&gt; has a
paragraph break first then the text.


<p>Blah blah blah</p>
<p>More blah blah blah</p>

Check if last tag is same level, if so do paragraph break.

The second test case has garbage before the doctype, so the second one is 
rendering in quirks mode. Both test cases render the same in IE6 and in the 
moz build from 2001121103.

this is a wfm for me
