pdf

Since: Buttons 1.0.0

Create and save a PDF file that contains the data from the table.
Please note - this property requires the Buttons extension for DataTables.

Description

This button type serves as a proxy that will automatically detect if the pdfHtml5 button can be used based on the browser's capabilities and the libraries available on the page.

This is provided as an option since the HTML5 button type requires a reasonably modern browser which may not always be available to the end user.

If the requirements of the pdfHtml5 button are not satisfied, no button will be presented to the end user. For the requirements of each button type, please refer to its own documentation.
