Hello Haijian,
I am running Vaadin 8 and using version 2.0.2 I export a grid in Excel.
I also use ExporterOption as indicated in the release notes.
However, it does not work as inclined. More specifically, I am not able to change the name of the column in the exported excel file, whatever I try.
How can I solve this problem?
Thank you.
Best regards,
Dimitris Soumis
