Настройка шрифта с помощью JavaScript через C++

Настройка настроек шрифта

Aspose.Cells предоставляет класс Workbook, который представляет файл Microsoft Excel. Класс Workbook содержит коллекцию worksheets, которая позволяет получать доступ к каждому листу Excel. Лист представлен классом Worksheet. Класс Worksheet предоставляет коллекцию cells. Каждый элемент коллекции cells — это объект класса Cell.

Aspose.Cells предоставляет методы класса Cell style и style, которые используются для получения и установки стиля форматирования ячейки. Класс Style предоставляет свойства для настройки настроек шрифта.

Установка названия шрифта

Разработчики могут применить любой шрифт к тексту внутри ячейки, используя метод name объекта Font.
