How to add a table row using alpinejs

Hi! I am trying to add table row by button click in a blade file. It's a standard Laravel 9 application with alpinejs pulled in.

The desired behaviour is that when someone clicks on the add replacement button, it should add an additional row in the table. While alpine js works and executes other commands like "$refs.partTable.remove()" , it fails to execute "$refs.partTable.insertRow(0)".

My Code is as follows:

<div x-data class="bg-white px-4 py-5 shadow sm:rounded-lg sm:p-6 sm:px-6 lg:px-8">
    <form action="/partReplacement" method="POST">
        @csrf
        <div class="sm:flex sm:items-center">
            <div class="sm:flex-auto">
                <h1 class="text-xl font-semibold text-gray-900">Part Replacement Details</h1>
                <p class="mt-2 text-sm text-gray-700">Please enter details of parts replaced</p>
            </div>
            <div class="mt-4 sm:mt-0 sm:ml-16 sm:flex-none">
                <button @click="$refs.partTable.insertRow(0)" type="button"
                    class="inline-flex items-center justify-center rounded-md border border-transparent bg-indigo-600 px-4 py-2 text-sm font-medium text-white shadow-sm">Add
                    Replaced Parts</button>
            </div>
        </div>
        <div
            class="-mx-4 mt-8 overflow-hidden shadow ring-1 ring-black ring-opacity-5 sm:-mx-6 md:mx-0 md:rounded-lg">
            <table class="min-w-full divide-y divide-gray-300">
                <thead class="bg-gray-50">

                            class="py-3.5 pl-4 pr-3 text-left text-sm font-semibold text-gray-900 sm:pl-6">
