DataTable adding row alert error "Requested unknown parameter" - datatable

Question

Here is the error prompt when I try to add a new row in my DataTable.
DataTables warning: table id=table-workshops - Requested unknown
parameter 'name' for row 39, column 0. For more information about this
error, please see http://datatables.net/tn/4
HTML
<table class="table table-bordered table-striped table-hover js-basic-example" id="table-workshops">
<thead>
<tr>
<th>Workshop</th>
<th>Number</th>
<th>Category</th>
</tr>
</thead>
<tbody></tbody>
</table>
jQuery
var workshops = JSON.parse(workshops_get());
var table = $('#table-workshops');
table.DataTable({
destroy: true,
data: workshops,
pageLength: 5,
columns: [
{data: 'name',},
{data: "number",},
{data: "category",},
],
order: [[0, 'asc']]
});
$(document).on('click', '.workshop-add', function(){
table.DataTable().row.add(['test', 'test', 'test']).draw();
});
Here is my table with loaded data (fine)
Here is my table with a new row but empty
I look at the multiple answers on the web but didn't find the solution for me.
I followed the doc of the official DataTable website.

Did anyone know where is the issue ?
Thank you.
