Dynamically adding/removing HTML table entries

I am developing a SPA using ASP.NET Core 3.1 Razor.

In one of the Create Model screens, I have a nested collection E.g "Create Customer" screen has to allow the user to add a collection of his/her Cars in this screen.

I have seen examples of dynamically adding HTML table rows but it doesn't seem to work in Razor SPA. Please help with any examples.
