title: Align checkable items in qTableWidget
body: <p>In tableWidget I have one column entirely made up of checkable items. 
  I can't figure out how to center the checkbox or at least remove the text-box next to it.
  As you can see on this picture <img src="https://i.stack.imgur.com/DzSdk.png" alt="enter image description here"> text-box has that ugly outline when I click on cell, I would like that turned off in entire table if it's possible.
  I've read that I need to use a delegates to control the positioning of items/icons, but for nooby like me it would take too long to understand that right, so if there is some simple solution that will make that column less ugly, please, examples would be appreciated.</p>
