Header and Footer
ExcelJS library allows you to customize worksheets outside the exported cell area. This demo uses this functionality to add a header (a title before exported data) and a footer (a note after exported data).
Review the onExporting handler to see the data export code. The functions that create header and footer sections utilize the following customization features:
- Merged cells
- Cell values formatting
- Font properties
- Text alignment
