Is it possible to make a checkered table in Ember.js using ONLY Handlebars and ember-composable-helpers

I'm new to Ember.js and I'm trying to make a simple checkered table. I'm using Bootstrap 4, ember-composable-helpers, and Handlebars. I want to know if anyone knows how to do this WITHOUT using javascript?

My mockup code is as follows however I don't know how to insert logic into the #if HBS helper:

<h1>Table</h1>
<table class="w-100">
    
    <tr class="">
        

            
                <td class="bg-dark"></td>
            
        
    </tr>
    
</table>

Should I just make a ternary class? Anywho I'd like to see if anyone knows just for knowhow purposes...
