Exporting data into PDF/XLS/XML/CSV formats using the DataExporter component

The DataExporter component provides the ability to export the DataTable data into various formats such as Excel, PDF, CSV, and XML. DataExporter provides options for:

• Exporting entire DataTable rows

<dependency>

  <version>2.1.7</version>
</dependency>
