Je voudrais :
- Récupérer dans une matrice en colonnes les en-têtes de colonnes
- Récupérer les unités dans une matrice
- Récupérer dans une autre matrice les données telles qu'elle sont présentées dans le fichier

Le code existant utilise la fonction importData mais les colonnes des qui contiennent au moins
une données n'étant pas en format numérique (exemple : **) ne sont pas prises en compte.

Avez-vous une solution à me proposer svp ?

Merci.
