For Vaadin 7 and Table, it does not ignore or hide collapsed columns. Is that on purpose? It only looks at “visible” columns from table.getVisibleColumns(). You can also see this if users reorder the columns on the frontend - the exporter does not export the same columns and order that are in the table on the frontend. Am I maybe doing something wrong?

I think I have the same problems with Vaadin 7 Grid, but I cannot remember right now.

I suppose I could get around this by making a different array of “visible columns” that hides the columns I don’t want to be visible and then call export.setVisibleColumns(reducedColumns). This doesn’t help with Vaadin 7 Tables, which let you reorder the columns, but that is a separate issue.

Sadly, I have not tried it in Vaadin 8 or Vaadin 10+ - no such apps right now. That said, eventhough the API is different, I suspect some of the basic principles can be applied here that can be applied in Vaadin 7.

export.setVisibleColumns(reducedColumns) does work, but when I click the button to download the excel, the table gets refreshed and the “collapsed” columns become uncalapsed. I guess the best option is to always limit the column visibility with table.setVisibleColumns(reducedColumns) instead of depending on table.setColumnCollapsed.
