If I select multiple fields (columns) and cmd-click one of them, it narrows the selection to that one field. If I select multiple fields and go to the dropdown for one, it narrows the selection to that one field. How do I delete multiple fields at once rather than having to go through them one by one? This seems like incredibly basic spreadsheet functionality and I’m puzzled that I can’t find it.
I think you can’t. Maybe you could ask for it in the Feature Request category.
