Hello Lai Yiqiang,

Hope you are doing well.

To make only one column of a tree view editable and open the form view while clicking other columns, in base odoo we cannot open form view for readonly fields so the another option that we have to add one button in tree view like below:

in your model:

def open_record(self):
# first you need to get the id of your record
rec_id = self.id
# then you need to get the form id
form_id = self.env.ref('module_name.form_xml_id')

# then open the form
return {
'type': 'ir.actions.act_window',
'name': 'title',
'res_model': 'your.model',
'res_id': rec_id.id,
'view_type': 'form',
'view_mode': 'form',
'view_id': form_id.id,
'context': {},
}

Thanks & Regards,
