Custom Spreadsheet Column Type

Jspreadsheet is a javascript data grid with spreadsheet-like controls that gives developers a lot of flexibility. The following example shows how to integrate a third-party clock plugin as a custom column. From version 8, the editor is created once, and it is the same during the entire lifecycle of the application.
