Wikipedia talk:Advanced table formatting

Where to request new extension to wikitable?
I'd like to be able to use a subclass, as in the following:

There are three cells in the table above that contain a 1. It would be good if these cells were automatically shaded (as has been manually done in the second row), without additional markup in the cells themselves. I know this to be possible using CSS, so the question is how can this be achieved in wiki?

I'm thinking I need to add

class="wikitable discog plainrowheaders" style="text-align:center;"

or similar. And then discog can be defined elsewhere.

Am I even in the right place to suggest this?

Any way to freeze the top row (header info) of a table?
Is there any way to freeze the top row of a table, the header info for the columns? So that the top row floats down the screen as user scrolls down the table, that is, so that in a table with many rows the viewer can scroll down through the rows to the desired item and still see the column header info.

 * That's way too useful a request to get any traction. They're too busy perfecting WP:Flow. EEng 23:17, 29 April 2019 (UTC)

Section on moving a column/row outdated Suggestion
The visual editor now allows whole columns/rows to be moved. That would be an easier method than hand editing.--Jessemulert (talk) 23:03, 25 April 2021 (UTC)

Set one column in italics?
Is there a way to set one column of a table in italics without marking each entry individually. I'm looking at List of trees and shrubs by taxonomic family where almost every entry in the column "Scientific name" should be in italics. I'm not terribly literate in the intricacies of tables, but I can follow directions if I can find them. Thanks, SchreiberBike &#124; ⌨ 17:34, 15 May 2022 (UTC)
 * has to be used for each item in a column. Since there are so many, I went ahead and made them italics using find and replace. Feel free to modify any that shouldn't be italics. Jroberson108 (talk) 21:40, 15 May 2022 (UTC)
 * Well, thanks a million. You've got some find and replace skills that go beyond my own, or you did a lot of it manually. Thank you and keep up the good work. (I will go in and fix some odd cases.) SchreiberBike &#124; ⌨ 00:36, 16 May 2022 (UTC)
 * You're welcome. I used a regular expression to find and replace them all in one go. I manually modified one to move the parenthesis outside the italics. I just saw that I missed a table in the second section, so I went ahead and did those too. Hopefully the bulk of it is done now. Jroberson108 (talk) 03:08, 16 May 2022 (UTC)
