Я работаю над системой посещаемости, где пользователь отмечает его посещаемость. На той же странице у меня есть календарь, показывающий текущий месяц.
Я хочу изменить цвет ячейки таблицы
1.Green для 'PRESENT'
2.Yellow для 'LEAVE'
3.Red для 'ABSENT'
Я ищу вам какую-то помощь, потому что я очень скоро отправлю свой проект в колледж. Ищите свою любезную помощь `
Вот базовый дизайн
