Selecting Multiple DataTable Rows using Shift+Click

[dansm...@gmail.com]

I was excited to see that the DT team has recently added support for using shift+click to select multiple rows in a datatable (http://editor.datatables.net/examples/simple/multiRow.html). Is there a way to use this feature with shiny-generated datatables?

In a basic example this the one below, multi-selection by clicking on one row at a time works perfectly, but enabling the shift-click behavior isn't as obvious to me.

# app.R

library(shiny)

shinyApp(

  ui = fluidPage(fluidRow(column(12, DT::dataTableOutput('tbl')))),

  server = function(input, output) {

    output$tbl = DT::renderDataTable(iris)

  }

)

Thanks!

I noticed that the reference manual for DT has a 'select.style' parameter that closely mirrors the 'selection' parameter of renderDataTable (http://datatables.net/reference/option/select.style). However, setting selection='os' causes termination with the error message "Error in gregexpr(calltext, singleline, fixed = TRUE) : regular expression is invalid UTF-8".

#app.R (this version does not run)

library(shiny)

library(DT)

shinyApp(

  ui = fluidPage(fluidRow(column(12, DT::dataTableOutput('tbl')))),

  server = function(input, output) {

    output$tbl = DT::renderDataTable(iris, selection='os')

  }

)

#app.R (runs, but no shift-click behavior)

library(shiny)
library(DT)

shinyApp(

  ui = fluidPage(fluidRow(column(12, DT::dataTableOutput('tbl')))),

  server = function(input, output) {

    output$tbl = DT::renderDataTable(iris, options=list(select.style='os'))

  }

)

Please let me know if you have any ideas. Thanks!

The DT package is using a custom implementation of row selections
instead of the official DataTables approach. We hope to catch up with
the official DataTables approach in the near future. For now, you
cannot use selection = 'os'. Sorry.
