Arguments

spec: TFL spec object

id: Footnote identifier (auto-generated if NULL)
styleRef: Character vector of style names or result of f_combine(). Merged with last-win strategy.
order: Order of footnote group (auto-assigned if NULL)

spec <- create_table(mtcars) |>
  add_footnote("Data source: Clinical database lock 2025-12-01") |>
  add_footnote("Missing values displayed as 'N/A'",
               styleRef = f_combine("i", "font_courier_new"))

# Multiple footnote lines in one group
