Hmm, let me think - do I know anyone using editableList? Maybe I do ... wait one ...
Here is a simple section taken from the uibuilder v2 admin panel:
<!-- ---- Hideable NPM Section ---- -->
<div id="npm-props">
<h3>Manage Front-End Libraries</h3>
<p>
Install, remove or update npm packages that provide front-end libraries such as
VueJS, jQuery, MoonJS, etc.
</p>
<p>
You can search for packages on the
<a href="https://www.npmjs.com/" target="_blank">official npm site</a>
or on <a href="https://npms.io/" target="_blank">npms.io</a>.
Take the name and paste it below then use one of the buttons.
</p>
<!-- Package List -->
<div class="form-row">
<ol id="node-input-packageList"></ol>
</div>
</div>
And here is some code to go with it:
RED.nodes.registerType('uibuilder', {
....
/** AddItem function for package list
* @param {JQuery<HTMLElement>} element the jQuery DOM element to which any row content should be added
* @param {number} index the index of the row

*/
function addPackageRow(element,index,data) {
var hRow = ''
if (Object.entries(data).length === 0) {
// Add button was pressed so we have no packageName, create an input form instead
hRow='<input type="text" id="packageList-input-' + index + '"> <button id="packageList-button-' + index + '">Install</button>'

// addItem method was called with a packageName passed
hRow = data
}
// Build the output row

Sorry, that's a bit of a dump, hopefully you can see how it is done.
While I'm not using columns as such, those are just some html and some CSS to control the width.
You can easily break up rows either wrapping elements with <div> or a simple <br> if you don't want paragraph spacing.
Think this 
... Do you perhaps know a node that I can use as an example?
