解决办法：

修改C:\ProgramInstall\Anaconda3\envs\py373\lib\site-packages\jet\utils.py文件的第223行

cl = ChangeList(request, model, list_display, list_display_links, list_filter, model_admin.date_hierarchy, search_fields,list_select_related, model_admin.list_per_page, model_admin.list_max_show_all, model_admin.list_editable,model_admin)

在后面新增 , model_admin.sortable_by

cl = ChangeList(request, model, list_display, list_display_links, list_filter, model_admin.date_hierarchy,search_fields,list_select_related, model_admin.list_per_page,model_admin.list_max_show_all, model_admin.list_editable,model_admin, model_admin.sortable_by)

就OK了
