I’ve found that when defining the table columns, you cannot define 'field': 'item.subitem'

while I found that it can be tricked by using

format (value) {
  return value.subitem
}

it doesn’t work when it comes to sorting

I’m trying to center some content in the center and middle of the page, but looks like the width is not filling.

am I doing something wrong here, or is this just not possible?

<div class="row gutter items-center">
  <div>
    <h1 class="text-center">HELLO</h1>
  </div>
</div>
