Hi,
Do you provide nested datatable in the latest version? If there is any possibility to export nested dataset to PDF?
Again, if there is any possibility to export two datasets to PDF via node.js? or JAVA?
Subviews (ability to nest any view included datatable) have been released within Webix 3.0, in the PRO edition: http://docs.webix.com/datatable__subviews.html
Nested datatables are not exported with the master datatable, so you will need to create a temporary grid to get them both to PDF.
We are going to rework export to PDF. As you might have already seen, the exportToPDF method is deprecated now and will be excluded from the library in 3.2 version.
