The default_fonts() function

Use exibble to create a gt table. Attempting to modify the fonts used for the time column is much safer if default_fonts() is appended to the end of the font listing in the cell_text() call (the "Comic Sansa" and "Menloa" fonts don’t exist, but, we’ll get the first available font from the default_fonts() set).

    style = cell_text(
      font = c(
        "Comic Sansa", "Menloa",
        default_fonts()
      )
    ),
    locations = cells_body(columns = time)
  )
