I have 2 questions with vue.js 2 and a fiddle here: https://jsfiddle.net/tmun9cxa/1/

  1. When you click a column header, why does my sorting not work? What is the solution?

  2. How do I go about making the search input field search only the pn column?

A lot of the examples ive found are using vue1 and out of date.

<input type="text" value="" v-model="search" placeholder="Search">

<table style="text-align: center;">
    <thead>
        <tr>
            <th v-for="column in columns">
                <a 
                    href="#"
                    v-on:click="sort(column.shortcode)">{{column.label}}
                </a>
            </th>
        </tr>
    </thead>
    <tbody>
        <tr v-for="(product) in products">
            <td>{{product.pn}}</td>
            <td>{{product.od}}</td>
            <td>{{product.id}}</td>
            <td>{{product.thickness}}</td>
            <td>{{product.lo}}</td>
            <td>{{product.weight}}</td>
        </tr>
    </tbody>
</table>

javascript here

        el: '#app',
