They do not in the current build. Here are a couple more sample links to show the problem. http://samples.msdn.microsoft.com/workshop/samples/author/dhtml/refs/colgroupEX1.htm http://samples.msdn.microsoft.com/workshop/samples/author/dhtml/refs/colgroupEX2.htm Reproducible: Always Steps to Reproduce: 1. Place the following code into an HTML page. <table border="1"> <colgroup span="3" style="color:#FF0000;"> </colgroup> <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> </tr> </table> Now the first 3 numbers should be red. They are not. Actual Results: The first 3 columns should contain red text. Expected Results: They do not turn red. It's a beta build. Something might have glitched in the build or what not. I figured I'd point it out so it can get on the "fix-it" charts. It's "supposed" to work so I set the severity to major. Did it work in previous beta builds? What about in 2.0.0.x?Component: General → LayoutProduct: Firefox → CoreQA Contact: general → layout No, it is not supposed to work, per the CSS 2.1 specs. only a limited number of properties can be applied to the col and colgroup elements http://www.w3.org/TR/CSS21/tables.html#columns If your bugreport means 'support the color property for colgroup', then this bug is INVALID. Additionally, HMTL 4 points to align attribute for col and colgroup http://www.w3.org/TR/html401/struct/tables.html#h-11.2.4 This is handled in bug 915.

Higher leveled item is set with a non-transparent property, it will not show the col level property. This is part of the layering architecture used in table layout design. Page < Table < Colgroup < Col < Rowgroup < Row < Cell All are assumed "transparent" and if a higher order element specifies a change, that takes precedence over the lower level elements attributes so, of course, if Row or Cell or Rowgroup (not directly stated in THAT link but there are only 3 "named" rowgroups -- THEAD, TFOOT, TBODY)... As to your reference to the HTML401 -- look at the "attributes defined elsewhere" -- note that "style" is listed there. That means both col and colgroup support inline style syntax, according to the HTML 4.01 spec and it works this way in at least IE. Thus your "no it's not..." is in correct. It is/was/should be supported according to the published spec. rowgroup and row support are there -- colgroup and col are missing. Whether it did or did not previously, I don't know and I've enough other projects I'm working on that I really can't take the time to go back and figure out how to get 2.x to load or uninstall the beta and try out 2.x or whatever it'd take. The sample code I provided can be put into any text editor, saved off to a simple "test.html" file and viewed from more than 1 browser or version of a browser to see how it works. I did take the time to test it on a far more complex test.html (for rowgroup, etc...). It's a plug ugly table but tests out a few different attribute support things... Just 'see what does/doesn't work basic HTML/CSS code flag testing.. ---- <HTML> <HEAD> </HEAD> <BODY> This example is a boatload of different tests for complex table architecture support. <table frame="border" border="5" rules="groups"> <colgroup span="3" style="background: #222222; color:skyblue;"> <col width="150px" align="center" valign="top"></col> <col width="120px" align="justify" valign="middle"></col> <col width="200px" valign="bottom" bgcolor="green"></col> </colgroup> <col width="50px" align="right" style="background:blue; color:pink"></col> <thead bgcolor="orange"> <tr> <th scope="colgroup"> First </th> <th> Second </th> <th> Third </th> <th scope="col"> Fourth </th> </tr> </thead> <tfoot style="border: 8px double orange"> <tr align="left" valign="top"> <td style="text-align: justify">this is tfooter stuff.

Yeah I guess so!</td> <td>3 is three</td> <td>4 is four -- one two three and four -- let us force line wrap to see how valign works.</td> </tr> </table> </BODY> </HTML> (In reply to comment #3) > (In reply to comment #2) > > No, it is not supposed to work, per the CSS 2.1 specs. > > only a limited number of properties can be applied to the col and colgroup > > elements > > http://www.w3.org/TR/CSS21/tables.html#columns > > If your bugreport means 'support the color property for colgroup', > > then this bug is INVALID. > > > > Additionally, HMTL 4 points to align attribute for col and colgroup > > http://www.w3.org/TR/html401/struct/tables.html#h-11.2.4 > > This is handled in bug 915. > > > If you read the w3.org statement what it says is "if both row and cell are set > to transparent" What that means is if a...

But CSS 2.1 explicitly mentions 4, and only 4, style properties that apply to col/colgroup (see link above in comment 2). MS IE bends the specs in this case (color, font-size, -style, -weight, etc). HTML 4 also mentions the align attribute, which is not or badly supported in most browsers, including Gecko (as noted above, bug 915; no need to comment in that bug, the issues are known and understood, thank you). --- PS In the future, please use the attachment feature of a bug report to attach test cases, it is much easier to review.Status: UNCONFIRMED → RESOLVEDClosed: 17 years agoResolution: --- → DUPLICATE (In reply to comment #4) > (In reply to comment #3) > > (In reply to comment #2) > > > No, it is not supposed to work, per the CSS 2.1 specs. > > > only a limited number of properties can be applied to the col and colgroup > > > elements > > > http://www.w3.org/TR/CSS21/tables.html#columns > > > If your bugreport means 'support the color property for colgroup', > > > then this bug is INVALID. > > > > > > Additionally, HMTL 4 points to align attribute for col and colgroup > > > http://www.w3.org/TR/html401/struct/tables.html#h-11.2.4 > > > This is handled in bug 915. > > > > > If you read the w3.org statement what it says is "if both row and cell are set > > to transparent" What that means is if a...
