Hide certain columns in a responsive data table using DT package

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:

Example output

enter image description here

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

colums2hide <- c('col_name_1','col_name_2')

This is how to do it with specifying column names vs column numbers.

I have another way which I like for its readability. It does not solve the problem of column numbering though.

library("shiny")
library("DT")
library(magrittr)
columns2hide <- match('Sepal.Width', colnames(iris))
shinyApp(
  ui = fluidPage(DT::dataTableOutput('tbl')),
  server = function(input, output) {
    output$tbl = DT::renderDataTable(
      {
        dataTableProxy(outputId = 'tbl') %>%
          hideCols(hide = columns2hide)
        iris
      },
      extensions="Responsive"
    )
  }
)

dataTableProxy creates a proxy object that you can operate on with a couple of functions (see ?dataTableProxy). It can be handy for hiding/showing/selecting/add/... rows and columns of the table when clicking on a button, for example. Because it has deferUntilFlush = TRUE by default it waits with its handling of the table until its next generation. In this case this simply happens on the following line.

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)))
