# Example 1 ----------------------------------
# build primary table
tbl <-
  cards::ard_stack(
    trial,
    .by = trt,
    cards::ard_summary(variables = age),
    cards::ard_tabulate(variables = grade),
    .missing = TRUE,
    .attributes = TRUE,
    .total_n = TRUE
  ) |>
  tbl_ard_summary(by = trt)

# create ARD with overall results
ard_overall <-
  cards::ard_stack(
    trial,
    cards::ard_summary(variables = age),
    cards::ard_tabulate(variables = grade),
    .missing = TRUE,
    .attributes = TRUE,
    .total_n = TRUE
  )

# add an overall column
tbl |>
