[FLOAT] Problem Centering <TABLE> with <DIV> tag


(Core :: Layout, defect, P3)






(Reporter: unapersson, Assigned: buster)




(Keywords: testcase)


(4 files)

Applying align=center or text-align: center to a DIV tag does not center tables
within it. Using a <center> tag, which is a "shortcut" for <div align=center>,
however does work.

See testcase for examples

This is a block or line problem. Reassigning.
Updating to default Layout Assignee...kipp no longer with us :-(
Why are you re-reassing layout bugs? Do NOT touch layout bugs.

The bugs are assigned to Kipp so they can stay neatly organized until we have a
new owner for the block/inline code.

mass moving all Kipp's pre-beta bugs to M15.  Nisheeth and I will
prioritize these and selectively move high-priority bugs into M13 and M14.

Attached file better test case
the fix for this is to account for both NS_STYLE_TEXT_ALIGN_MOZ_CENTER and 
NS_STYLE_TEXT_ALIGN_CENTER in nsBlockReflowContext::AlignBlockHorizontally().  
Same for NS_STYLE_TEXT_ALIGN_MOZ_RIGHT, while I'm at it.
Whiteboard: fix in hand
moving all buster m15 bugs to m16.

fix checked in.  should be able to verify against 4/17/00 build.

NOT fixed for Linux. Verified on 2000-07-13-08-M17 build.
The text and the cell are left justified for 2nd and 4th row.
But, they should be centered and right aligned respectively.

Reopening per Bindu's last comments.
extremely odd.  this is totally xp code.  I don't know why linux would behave
differently.  how does mac look?
Note that I changed some of the behavior when fixing bugs 37083 and bug 40038
(so that 'text-align: center' doesn't center blocks, since there was no evidence
that real sites depended on that quirk).
needs investigation.  won't make RTM, marking Future.
Target Milestone: M16 → Future
On my Linux trunk build from a few days ago, all the testcases are correct as I
think they should be in both quirks and standard mode (HTML's align centers
blocks, CSS's text-align works according to the CSS spec).
Upon managerial request, adding the "testcase" keyword to 84 open layout bugs that
do not have the "testcase" keyword and yet have an attachement with the word
"test" in the description field. Apologies for any mistakes.

text-align: when applied to block elements affects their inline content,
not the element itself, as per
<TABLE> is a block element NOT an inline element as defined in HTML:

I agree with David Baron. tables in 2nd and 4th rows *should* be left justified
To center the tables themselves { margin-left: auto; margin-right: auto; }
should be applied.

This bug seems to be fully resolved and works correctly for me.

The auto margins go on the table itself, not the div containing the table.
OK. Removing the DIV around the table and adding the definition 'TABLE {margin-
left: auto; margin-right: auto;}' to my style element causes part of the table 
to be centered: the caption is still off at the left of the page. The inline 
caption element is contained within the block table element. Is this a 
different bug?

It's not a bug.  CSS2 17.4.1 says:  "Captions above or below a 'table' element
are formatted very much as if they were a block element before or after the
table, except that (1) they inherit inheritable properties from the table, and
(2) they are not considered to be a block box for the purposes of any 'compact'
or 'run-in' element that may precede the table."  You'd need to add the same
auto margins to the caption.
I understand. Thank you for your patience. I agree that this bug is resolved.
Netscape's standard compliance QA team reorganised itself once again, so taking 
remaining non-tables style bugs. Sorry about the spam. I tried to get this done 
directly at the database level, but apparently that is "not easy because of the 
shadow db", "plus it screws up the audit trail", so no can do...
