ExcelJS

Задача - сделать Excel-подобную таблицу с поддержкой простейших формул. Пересчёт значений в ячейках должен происходить сразу при потере фокуса и затрагивать только те ячейки, значения которых затронуты. Пересчитывать каждый раз всю таблицу (если нет необходимости) нельзя. Использовать чистый JS (ES6), HTML, CSS. Использовать стороннние фреймворки, библиотеки не надо. Только то, что предоставляет браузер. Будет проверяться на последней версии chrome (десктопный и мобильный).

Размер таблицы пусть будет 100x1000 (ШxВ)
