Choose filetype for download button in Table (to xlsx)

I think it would be very useful if we could be able to choose the filetype for the "Download Button" in a table.

Currently it is only possible to choose between formatted CSV or raw CSV.

In the event handler (which cannot control the download button event) for the export of data you are able to choose between:

  • CSV
  • TSV
  • JSON
  • Excel (very important for non tech-savy users!)
