Change header text by icontext

[rdornas]

Hello! First of all, thanks for this great package!

Imagine I have the following df:

df <- tibble::tribble(
           ~Ciclo, ~Adequada, ~Atenção, ~Inadequada,
   "1ª avaliação",     0.789,      0.152,       0.058,
   "2ª avaliação",     0.923,      0.066,       0.011,
   "3ª avaliação",     0.957,      0.043,           0
   )

I've been trying to replace only some of the headers by icontexts but without success. In this case, I want Adequada to be a green "circle_check", Atenção to become a yellow "circle_alert" and Inadequada to be a red "circle_remove". In this way, the column header Ciclo would remain the same.

Is it possible to achieve this with formattable?

Thank you very much in advance!
