How could I fill out a custom column in the Orders grid?
Create a column in the grid and in the sales_order_grid table of the database, all correct up to this point. However now I need to load data into this column, as I could fill in this data from the corresponding column in the admin Sales> Orders (order view). I hope some answer that allows me to get out of this problem.
I await your answers, magento 2.2.2
