Я создал файл Excel для чтения.я могу установить значение ячейки на основе sheetName, colName, rowNum и данных, но я не могу создать метод, который будет устанавливать значение ячейки на основе имени листа, colno, rowno и данных .Итак, как создать метод с использованием вышеуказанного параметра и установить значения ячеек.получить метод данных ячейки и установить данные ячейки оба метода работают без ошибок.
