DevExtreme - Data Grid - New Excel Export API Update (CTP in v19.1)

In the v19.1 timeframe we started work on ExcelJS-based export functionality for the Data Grid widget, and you may remember that we previously posted about our early results. We have had lots of feedback since then, and we’ve been able to address common questions by creating additional demos, improving and extending our implementation as we went along.
