See the data in a table
An easy first step in exploring a dataset is to simply view it as a table.
So far we have focused mostly on inputs—interactive widgets that allow the user to select values. Now we want to have a table in our app, and send data to display in the table. To display objects in Shiny, we need to use output and render functions.

Case Studies: Building Web Applications with Shiny in R
Exercise instructions
Given a minimal Shiny app, add a table that will show the gapminder dataset. Specifically:
- Add a placeholder for the table by creating a table output with ID "table" in the UI.
- Use the corresponding render function in the server code to render the table.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
ui <- fluidPage(
h1("Gapminder"),
# Add a placeholder for a table output
___
)
server <- function(input, output) {
# Call the appropriate render function
output$table <- ___({
# Show the gapminder object in the table
gapminder
})
}
shinyApp(ui, server)
