title: Fix width of a DT in shiny
body: <p>I'm trying to fix the width of very wide table in <code>shiny</code> but haven't mange to do it. I try the answer here <a href="https://stackoverflow.com/questions/31921238/shrink-dtdatatableoutput-size">Shrink DT::dataTableOutput Size</a> but it didn't work, I also tried the answer from here <a href="https://github.com/rstudio/DT/issues/29" rel="nofollow noreferrer">https://github.com/rstudio/DT/issues/29</a> with percentage and pixels for all the columns and it didn't work neither. This is an example of the table and problem I have:</p>
  
  <pre><code>shinyApp(
      ui = fluidPage(
        DT::dataTableOutput("table")
      ),
      server &lt;- function(input, output) {
        x &lt;- cbind(iris,iris,iris,iris)
        output$table &lt;- DT::renderDataTable(x)
      }
    )
  </code></pre>
