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.
