title: Shiny renderDataTable | how to limit text size displayed
body: <p>While displaying a data table in shiny</p>
  
  <pre><code>output$tab1 &lt;- renderDataTable({
  expr = tbl
  }, options = list(orderClasses = TRUE,
                    lengthMenu = c(3, 5, 10),
                    pageLength = 3)
  </code></pre>
  
  <p>I would like to limit the text in each cell to 30 characters. Is there an option for that in order to facilitate the reading?</p>
  
  <p>I tried the solution of package DT (<a href="http://rstudio.github.io/DT/" rel="nofollow">http://rstudio.github.io/DT/</a>, see section 2.5.4 column rendering) but I was unsuccessful (I want to use renderDataTable with my current list of options)</p>
  
  <p>Many thanks in advance for your help!</p>
  
  <p>Regards,</p>
