Calculateur wattmètre et Couleur de table conditionnelle selon la valeur
loll
je sais pas si c'est faisable en JavaScript, mais dans Excel il y a le formatage de boite conditionnelle, et j'ai fait une application forte utile pour un premier coup d’œil sans même regarder le résultat à savoir si mes données sont bonnes, moyennes ou mauvaises. ( les valeurs utilisées avant un changement de couleurs sont dans la capture ici-bas )
