Sometimes an all-capitalized look is suitable for a table. With the opt_all_caps() function, we can transform characters in the column labels, the stub, and in all row groups in this way (and there's control over which of these locations are transformed).

  all_caps = TRUE,
  locations = c("column_labels", "stub", "row_group")



A table object that is created using the gt() function.


A logical value to indicate whether the text transformation to all caps should be performed (TRUE, the default) or reset to default values (FALSE) for the locations targeted.


Which locations should undergo this text transformation? By default it includes all of the "column_labels", the "stub", and the "row_group" locations. However, we could just choose one or two of those.


An object of class gt_tbl.


This function serves as a convenient shortcut for <gt_tbl> %>% tab_options(<location>.text_transform = "uppercase", <location>.font.size = pct(80), <location>.font.weight = "bolder") (for all locations selected).
