It would be a great to have a function to export the table content to CSV, Excel and PDF from the frontend. So you have a dropdown to select export as ... and then have the data in the selected format. Also the charts for Excel and PDF.
In Excel and PDF included the formatting and in CSV format just the values.
Therefor I also expect that you have the option in the setting for the table to enable/disable it for each table.
Additional to export an table it could be usefule to be able to export all tables and chart shown on one article at once in one file. Like each table on an seperate excel sheel or pdf page.
