gt_output: Create a *gt* display table output element for Shiny

In gt: Easily Create Presentation-Ready Display Tables

Create a gt display table output element for Shiny

Description

Using gt_output() we can render a reactive gt table, a process initiated by using render_gt() in the server component of a Shiny app. gt_output() 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 render_gt() is needed as the outputId in gt_output() (e.g., server: ⁠output$<id> <- render_gt(...)⁠; ui: ⁠gt_output(outputId = "<id>"⁠).

Usage

gt_output(outputId)

Arguments

outputId

Shiny output ID ⁠scalar<character>⁠ // required An output variable from which to read the table.

Value

An object of class shiny.tag.

Examples

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)
