R Shiny renderDataTable show two decimal places and center align all data

Question

I am trying to only show two decimal places for all data in my table and align everything centrally. The first column is countries, but the rest are numbers. This is the code

output$Composite <- renderDataTable(FVI_DATA_COMPOSITE, options = list(pageLength = 15,lengthChange=FALSE))

Any idea how to do that?

Edit: This does not work.

output$Composite <- renderDataTable(FVI_DATA_COMPOSITE, 
  options = list(pageLength = 10,lengthChange=FALSE), round(FVI_DATA_COMPOSITE[3:9], digits=2)

Answer 1

output$Composite <- renderDataTable(datatable(FVI_DATA_COMPOSITE, 
  options = list(pageLength = 10,lengthChange=FALSE)) %>% formatRound(c(3:9), 2)

Documentation here

Edit: To center align

output$Composite <- renderDataTable(datatable(FVI_DATA_COMPOSITE, 
      options = list(pageLength = 10,lengthChange=FALSE)) %>%
      formatRound(c(3:9), 2) %>% 
      formatStyle(columns = c(3:9), 'text-align' = 'center')
