Я пытаюсь создать разумно настроенную таблицу данных в Shiny.Вот некоторые из функций, которые я включаю: заголовки фильтров, столбцы в цветном / диапазоне форматов, полоса прокрутки X и полоса прокрутки Y, замороженные панели (первый столбец и все заголовки).У меня довольно много проблем с DataTable.
Некоторые проблемы связаны с фильтрами заголовков для столбцов в правой части таблицы, которые сдвигаются вправо при нажатии на них (и не фильтруются должным образом), а также с полосой прокрутки Y.
Внизу этой страницы я добавлю данные, чтобы попробовать себя.Спасибо.
