title: How to use formatPercentage and renderDataTable together
body: <p>I'd like to use <code>formatPercentage</code>,<code>rowname=FALSE</code> in renderDataTable. See below code Method 1 contains <code>formatPercentage</code> and Method 2 contains <code>rowname=FALSE</code>. I'd like to merge them together but keeps getting errors (<code>renderDataTable ignores ... arguments when expr yields a datatable object; see ?renderDataTable</code>). How do I do this? </p>
  
  <p>Method 1 contains <code>formatPercentage</code> but can't pass renderDataTable options:</p>
  
  <pre><code># Method 1 format Percentage 
  output$funddetails &lt;- DT::renderDataTable(
        DT::datatable({
        heatmap_raw[heatmap_raw$Keeper%in%
                      input$selectkeeper&amp;month(heatmap_raw$period)%in%
                      input$selectmonth,c("apid","Fund Name","Status","Comments","Last Update by Keeper","Most Recent Portfolio")]
        })%&gt;%formatPercentage(1, 2)
  )
  </code></pre>
  
  <p>Method 2 only contains options for renderDataTable but I can't use formatPercentage:</p>
  
  <pre><code>#Method 2
  data_fund &lt;- reactive({
      heatmap_raw[heatmap_raw$Keeper%in%
          input$selectkeeper&amp;month(heatmap_raw$period)%in%
          input$selectmonth,c("apid","Fund Name","Status","Comments","Last Update by Keeper","Most Recent Portfolio")]
  })
  
  output$funddetails &lt;- DT::renderDataTable(
    data_fund(),
    rowname=FALSE,
    options = list(
      pageLength=10,
      #autoWidth = TRUE,
      lengthMenu = list(c(25, 50, -1), c('25', '50', 'All')),
      searchHighlight = TRUE,
      scrollX=TRUE
    )
  )
  </code></pre>
