The fmt_percent() function

Use a summarized version of the pizzaplace dataset to create a gt table. With fmt_percent(), we can format the frac_of_quota column to display values as percentages (to one decimal place).

pizzaplace |>
  dplyr::mutate(month = as.numeric(substr(date, 6, 7))) |>
  dplyr::count(month, name = "pizzas_sold") |>
  dplyr::mutate(frac_of_quota = pizzas_sold / 4000) |>
  gt(rowname_col = "month") |>
  fmt_percent(
    columns = frac_of_quota,
    decimals = 1
  )
