24112 - TFOOT rendered above TBODY

Status: VERIFIED FIXED

(Core :: Layout: Tables, defect, P2)

Description

[Robin Lionheart]

If a table is specified with THEAD/TFOOT/TBODY row groups (in the correct order), Mozilla erroneously renders the TFOOT row group before the TBODY row groups rather than after. (It appears that Mozilla ignores row group tags altogether.)

This is contrary to the HTML 4.0 specification:

In nightly build 2000011508, when the optional closing tag </TFOOT> is omitted, any following <TBODY> groups appear as a subtable beneath the <TFOOT> group. When the </TFOOT> closing tag is included, the <TFOOT> group is correctly positioned after the <TBODY> groups.

Harish, the content model is wrong for

<table border>
 <thead><tr><td>head
 <tfoot><tr><td>foot
 <tbody><tr><td>body
</table>

The real problem here is that elements are being closed out properly. If you
manually add the right close tags, the page lays out right. It looks like an
autoclosure bug in the navDTD.

FIXED by adding TD|TH to the autoclose tag list of TBODY,THEAD,and TFOOT.

Comment 5

[Christine Hoffman]

Using 2/1 build, verifying bug fixed. Using the 1/16 small testcase, tbody 
renders above tfoot as expected.

In accordance with "4xp for 'competitor products' Considered Harmful" thread on
n.p.m.qa.general, stripping the [4.xP] off this bug, though it's moot now.
