Hide certain columns in a responsive data table using DT package

Question

I am trying to create a responsive data table for my shiny application using DT package. I want to hide certain columns in advance. For example:

library("shiny")
library("DT")
shinyApp(
  ui = fluidPage(DT::dataTableOutput('tbl')),
  server = function(input, output) {
    output$tbl = DT::renderDataTable(
      iris,extensions="Responsive"
    )
  }
)

This output gives me 5 columns. It only hides columns when I narrow the page. But, I want to hide last 3 columns in advance and I just want to see first two columns every time. Is there a way to do that?

Update:

Answer 1

You can hide columns in your table using DT options or extensions.

If you want them to be hidden in advance but have a button to make them visible again, the ColVis extension should work well for you: link

If you just want thme stay hidden, add the following option (can't remember where I've seen its documentation right now..)

options=list(columnDefs = list(list(visible=FALSE, targets=columns2hide)))
