title: JAVA Apache POI Excel: add borders to cell range
body: <p>Is there a way to add borders to a cellrange using Java with Apache POI?</p>
  
  <p>Like A1:B2 should get a top-bottom-left-right thick border - style?</p>
  
  <p>I know how to create &amp; apply styles to single cells and I might iterate trough the cells and apply the appropriate styles but I'm sure there's an easier way.</p>
