How to always display 3 decimal places in DataTables in R Shiny? [closed]

You can use DT::formatRound function. It take list of columns and number of digits to render:

library(DT)set.seed(323)data.frame(x=runif(10), y=rnorm(10), z=rpois(10, 1)) %>%    datatable() %>%    formatRound(columns=c('x', 'y'), digits=3)

enter image description here

Just remember about using DT::renderDataTable in the server function and DT::dataTableOutput in the UI.
