285184 - CSS not rendered for table col or colgroup

Status: RESOLVED INVALID

(Core :: CSS Parsing and Computation, defect)

Description

[Nicholas Shewmaker]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.6) Gecko/20050223 Firefox/1.0.1

I have created a <table> structure and am trying to format it with CSS (see
attached code). I want the data in the first column to be in bold, so I set
"col#first" to do so, with no results.  "col#first td" also failed, even when I
set all "td" to explicitly inherit font-weight.  The same is true for all col's
in my table (it's not just a case of the first one).

"col#first" does successfully set the background-color of all included cells
(the column).

Reproducible: Always

Steps to Reproduce:
<style type="text/css">
td {
	font-weight: inherit;
	color: inherit;
}
col#first {
	font-weight: bold;
	color: red;
	background-color: yellow;
}
col#first td {
	font-weight: bold;
	color: green;
	background-color: blue;
}
</style>
...

<table>
	<col id="first" />
	<col id="second" />
	<col id="third" />
	<tr>
		<td>should be bold</td>
		<td>1-2</td>
		<td>1-3</td>
	</tr>
	<tr>
		<td>should be bold</td>
		<td>2-2</td>
		<td>2-3</td>
	</tr>
</table>


Expected Results:  
The elements in the first column should inherit the settings of col#first.

I'm not sure what the CSS2.1 spec says for this situation, but the HTML4.1 spec
says "the COL element shares its attributes with all the columns it spans". IE
renders as I would expect, but that just leads me to suspect that my
expectations don't match the specifications. ;)

Yeah, you can only set borders, background, width and visibility. See

In addition <col class="xxx"> is ignored.

html401:
The COLGROUP element 

<!ELEMENT COLGROUP - O (COL)*          -- table column group -->
<!ATTLIST COLGROUP
  %attrs;                              -- %coreattrs, %i18n, %events --
  span        NUMBER         1         -- default number of columns in group --
  width       %MultiLength;  #IMPLIED  -- default width for enclosed COLs --
  %cellhalign;                         -- horizontal alignment in cells --
  %cellvalign;                         -- vertical alignment in cells --
  >

this includes style, class etc.

So my guess its not implemented correctly in FF, and the correct way in IE??

Note that we do support backgrounds on columns, and bug 915 covers inheritance of the HTML attributes that HTML4 says should be inherited.
