But it doesn’t work, I cant add a file to any row with QuickEdit, and in this QuickEdit article says, that it should be posible since file type columns are not in the restricted list.
You should have mentioned you can’t even edit the file column. That’s likely the problem, not drag-and-drop. Please post a screenshot of the column configuration. If the column has Valid if and/or Editable? expressions, please also post screenshots of them.
I’ve never tried to drag and drop files or upload through a table view, but from from the screenshot it looks like the problem might be the fact that the system auto-generates an inline “view file” action for File-type columns, combined with the behavior of the Table view that causes inline actions to replace the corresponding values rather than being shown alongside them. So you’re just seeing the “view file” action showing up there. If you hide the action or make it not inline, it might cause the File input to appear in the table (I haven’t confirmed this but it could be worth a try).
Actually I moved the View file inline button from the Certificados column to Prominent, so the coloumn wouldn’t be obstructed by the acttion button. Yet the result is the same, I can’t modify the column, neither drag and drop anything in it.
I think you’re right… Just read this post where they mention that QuickEdit for view doesn’t work on Image columns only in detail view, sadly it looks the same for File.
