How do I format columns of a datatable using renderDataTable() in the DT package?
<p>I can format a column of a datatable object like so</p>

<pre><code>library(DT)
datatable(data.frame(Amount=c(1.00, 2.20, 4.15))) %&gt;% formatCurrency(columns='Amount')
</code></pre>

<p>But how can I do this using <code>renderDataTable()</code>?</p>

<pre><code>library(shiny)
library(DT)

ui &lt;- shinyUI(fluidPage(
  DT::dataTableOutput('dtoMyTable')
))

server &lt;- shinyServer(function(input, output){
  output$dtoMyTable &lt;- DT::renderDataTable({
    data.frame(Amount=c(1.00, 2.20, 4.15))
  })
})

shinyApp(ui = ui, server = server)
</code></pre>
