Advanced Document Customization
DevExtreme provides a utility that integrates its widgets with ExcelJS (an Excel document customization library). In this demo, this utility is applied in the onExporting event handler and used to add a custom header and footer and other customization to an Excel document exported from the DataGrid widget.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
