GIS beginner here...
I have a tab-delimited text file that I'm importing into QGIS just fine. But I try to edit the attribute table, the little pencil-looking button is grayed out, and it's not letting me edit it via the QuickMultiAttributeEdit plugin either.
I've googled around a lot, but can't for the life of me figure out how to make the attribute table editable. Any help?
