Tables: TableQueueSetColumnDisplayOrder() enforce handling ImGuiTableColumnFlags_NoReorder as advertised: can't reorder through them. (#9312)

Browse Source 
This would never using interactive reordering as reordering from headers was done on a 1 by 1 basis which was already covered in the test.
Hard to tell what's a sensible design for this tbh. Expecting _NoOrder columns to be sequential and leading/trailing anyhow.
