ft <- set_header_df(ft, mapping = typology, key = "col_keys" )
ft <- merge_h(ft, part = "header")
ft <- merge_v(ft, j = "Species", part = "header")
ft <- theme_vanilla(ft)

  col_keys = c( "Sepal.Length", "Sepal.Width", "Petal.Length",
                "Petal.Width", "Species" ),
  unit = c("(cm)", "(cm)", "(cm)", "(cm)", ""),
