Js data manipulation problem

problem description

the user selects three arrays as follows 

let colorOptions = ["",""]
let sizeOptions = [36,37,38,39,40,41]
let otherSizeOptions = ["A","B","C","D"]

I want the following results

now this problem has not been solved. I hope the big guys can help me solve it. Thank you very much. If there is a better way to solve the problem, my data operation is very weak, and I have been learning. Thank you

Is

using vue? If you are using vue, then consider using computed, to calculate the displayed array based on the three selection results, and then check the main dimensions of 36 hr class= 37 answer 38, and then use the set function of computed to set sizeOptions

< hr class= "array" >

use vue to write a demo, that can run. Adjust the style by yourself

Thank you for inviting me. I took some time to write a demo, that I hope is the effect you want. https://jsfiddle.net/fd1ovqp2.
