Is there a way to include in the options for each widget tab in the AttributeTable widget, a button to export all rows and columns to PDF? Something that is below the "Export All to CSV" button.
You would have to find and acquire some JS library that supports creating a pdf and do custom development to add that as a export option (no small task).
Would you then like to export the grid to a less labor intensive format like HTML?
I guess you could. I am not sure it would be any less effort though.
