React Data Grid - Header and Footer
The DataGrid allows you to customize a header and a footer in the exported PDF file.
To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.

Follow the steps below to configure a header/footer:
-
Call the exportDataGrid(options) method.
-
Use the following API to specify header/footer layout settings:
-
For a header
Use the topLeft object to specify a start position for DataGrid export. This position should be below the header. -
For a footer
Use the customDrawCell function to calculate the coordinates of the last right cell of the DataGrid.
-
-
Execute a promise after the exportDataGrid(options) method. In this promise, specify position and appearance of the header/footer.
