Can I add custom columns to the product table?
Yes! WooCommerce Product Table supports many different column types.
Custom field and taxonomy columns
You can add a custom column to store extra data by creating a custom field and displaying it in the product table. If you want to sort or filter the table by the extra data then you should use custom taxonomies instead.
Creating columns programmatically
WordPress developers can also add columns programmatically. Please refer to this hook in the developer documentation.
