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.

演習の手順
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.
