How can I pretty print a data frame in Zeppelin/Spark/Scala?

Question

I am using Spark 2 and Scala 2.11 in a Zeppelin 0.7 notebook. I have a dataframe that I can print like this:

dfLemma.select(\"text\", \"lemma\").show(20,fals

In Zeppelin you can use z.show(df) to show a pretty table. Here's an example:

val df = Seq(
  (1,1,1), (2,2,2), (3,3,3)
).toDF("first_column", "second_column", "third_column")

z.show(df)
