一.EditorManager
Handsontable.EditorManager is a class responsible for handling all editors available in Handsontable. If Handsontable.Coreneeds to interact with editors it uses Handsontable.EditorManager object. Handsontable.EditorManager object is instantiated in init() method which is run, after you invoke handsontable() constructor for the first time. The reference for Handsontable.EditorManager object is kept private in Handsontable instance and you cannot access it. However, there are ways to alter the default behaviour of Handsontable.EditorManager, more on that later.
