Description
The table exporter is very slow when exporting raw data and the user has selected to export reporter columns. The reason is that the main query is only loading the raw data. The associated reporters are loaded one by one which takes a long time when the data set is large. On my development machine a data set with 36K entries takes about 4 minutes to export.
The fix is to include a "fetch join reporters" in the query. This is already done in the query for the list page.

It should of course be a 'fetch join'.
