depending on what skin you use there might be a certain class you have to add, e.g. wikitable

could you share a link to the page on your wiki?

[near wadi]

it uses var(--background-color-button-quiet--hover) which is rgba(0,24,73,0.027)
I don't really get why you need to clone the wikitable class to wikitable-large though if you could just add both classes to the table and then do

.wikitable-large {
   --background-color-button-quiet--hover: rgba(230,0,85,0.027);
}

this way you wouldn't need any special styles for wikitable-large anymore

[near wadi]

it does work if your table has both the wikitable and wikitable-large class

just add both

you don't need any of the styles for wikitable-large that wikitable already has
elements can have multiple classes so you can just extend wikitable with wikitable-large

class="wikitable wikitable-large"

then your wikitable-large doesnt need any of the styles except for the ones that should be different from wikitable

you don't let the css know, you just give the element both classes in the html

and in the css you only specify the styles different from wikitable
