Table row used within models-table/table-body.

Component used when all columns are hidden and no data items are shown. Usually it contains a simple message.

Usage example:

<ModelsTable @data={{data}} @columns={{columns}} as |MT|>
  <MT.Table as |Table|>
    <Table.Body as |Body|>
      {{#if Body.allColumnsAreHidden}}
        <Body.ColumnsHidden as |CH|>
          Any message here
        </Body.ColumnsHidden>
      {{else}}
        {{! ... }}
      {{/if}}
    </Table.Body>
    {{! ... }}
  </MT.Table>
  {{! .... }}
</ModelsTable>
