gt_output | R Documentation |
Using gt_output()
we can render a reactive gt table, a process
initiated by using the render_gt()
function in the server
component of a
Shiny app. The gt_output()
call is to be used in the Shiny ui
component,
the position and context wherein this call is made determines the where the
gt table is rendered on the app page. It's important to note that the
ID given during the render_gt()
call is needed as the outputId
in
gt_output()
(e.g., server: output$<id> <- render_gt(...)
; ui:
gt_output(outputId = "<id>"
).
We need to ensure that we have the shiny package installed first. This
is easily by using install.packages("shiny")
. More information on creating
Shiny apps can be found on the Shiny website.
gt_output(outputId)
outputId |
Shiny output ID
An output variable from which to read the table. |
An object of class shiny.tag
.
Here is a Shiny app (contained within a single file) that (1) prepares a
gt table, (2) sets up the ui
with gt_output()
, and (3) sets up the
server
with a render_gt()
that uses the gt_tbl
object as the input
expression.
library(shiny) gt_tbl <- gtcars |> gt() |> fmt_currency(columns = msrp, decimals = 0) |> cols_hide(columns = -c(mfr, model, year, mpg_c, msrp)) |> cols_label_with(columns = everything(), fn = toupper) |> data_color(columns = msrp, method = "numeric", palette = "viridis") |> sub_missing() |> opt_interactive(use_compact_mode = TRUE) ui <- fluidPage( gt_output(outputId = "table") ) server <- function(input, output, session) { output$table <- render_gt(expr = gt_tbl) } shinyApp(ui = ui, server = server)
