Grid + ButtonIcon

I’m trying to put a button with icon in a column in the Grid, but in vaadin documentation says:
“No column icons; you can implement them in a column with an ImageRenderer.”
(quote link: )

Then I searched some forums a possible solution:
I’ve tried to implement the topic:!/thread/9225584/10837317,

but the results were as follows:

  • Display the image in the “Voltar”
  • Just show HTML FontAweseome the button in the column “Excluir”

Does anyone know another method to include the icon?
