Table property rowClassName not working as expected on fixed columns after V5

[balboFK]

Reproduction link

Steps to reproduce

Click on a row and look at the "Age" column, it should have its background colored as red and not change the background from the "Full Name" column

What is expected?

In Antd v4 you could pass styles like I did on the example and it would correctly apply to the "fixed" columns and not overwrite the styles passed directly on the columns with "onCell" property.

What is actually happening?

Styles are not applying to fixed rows unless you use "!important", but using "!important" also changes the color of the columns that use the property "onCell"

Environment	Info
antd	5.0.3
React	^18.0.0
System	Windows 10
Browser	Brave

---

Using "!important" is not a way of fixing it, since it changes the coloring of the columns that use the property "onCell" to change the backgroud. For row selection also, should be easier to disable the hover, as you can see on the example, unless you apply a style over the hover property, it changes the color back to white on hover.

Hi, I noticed that v5 added a style to a fixed column that caused the rowClassName property to not work as expected.

We could solve the styling problem here by unfixing the columns, but I think we could add a new feature in v5 that controls whether or not we want to use unfixed column styles via a field.

Perhaps the css scheme makes rowClassName less prioritized

Yes, that solves the problem, but for smaller screens i can't unfix the columns, sadly. Your point seems like a good idea, i think we should either have control of that, or let the styling work as before even with the new css scheme.

Hello again! Can we get some light on this one by one of the maiteners? @li-jia-nan @MadCcc @afc163 ?

I tried reproducing it on my project which uses SASS and it didnt really work at all, but I think that might be scss class handling fault, on this case with pure CSS it worked fine. I switched the sass to css and it worked fine.
