[SalesForce] lightning:dataTable URL won’t open in new window

I've got a lightning:dataTable I'm working on for a client. One of the columns is of type URL, and it links to a Visualforce PDF. It is defined in the columns attribute as:

{
  sortable:true, 
  label: 'Invoice No.',
  fieldName: 'urlField__c',
  type: 'url' , 
  typeAttributes: { 
    label: { fieldName: 'Invoice_Number__c' }, 
    target:'_blank'
  }
}

When the component loads, I can "Inspect Element" in Chrome and see that the URL correctly has target=_blank. However clicking it always opens the PDF in the same window under the Lightning header instead of popping open a new one. Then the user has to hit the back button to return to where they were which is not intuitive.

Is there anything I can do to force it to a new window?

typeAttributes: {label: { fieldName: 'Invoice_Number__c' }, target: '_top'}},
