title: How can I pretty print a wrappedarray in Zeppelin/Spark/Scala?
body: <p>In <a href="https://stackoverflow.com/questions/44946620/how-can-i-pretty-print-a-data-frame-in-zeppelin-spark-scala/44947118?noredirect=1#comment76874375_44947118">this</a> question I was told how to print a dataframe using zeppelin's z.show command. This works well except for 'WrappedArray' appearing in the lemma column: 
  <a href="https://i.stack.imgur.com/RLdBS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RLdBS.png" alt="enter image description here"></a></p>
  
  <p>I have tried this:</p>
  
  <pre><code>z.show(dfLemma.select(concat_ws(",", $"lemma")))
  </code></pre>
  
  <p>but it just gave me a list of words, not nicely formatted and I also want the racist column in my output.
  Any help is much appreciated.</p>
