if anyone still needs a solution for this:
just go create a client script or a new js file with the name yourdoctype_list.js
follow the documentation on how to add script for list view here:
then add the following script to the onload event:
frappe.listview_settings['Item'] = {
onload : function(listview) {
cur_list.columns.push({
type: "Field",
df: {
label: __("Created By"),
fieldname: "owner",
},
});
cur_list.refresh(true)
}
}
