Add wholesale price column in admin product list

[david-k]

Hello, I have a question - in backeng, when you click on Catalog and Products, you see product list and there are columns like "id, product name, price, stock quantity" and so on in the table. I need to add there new column - wholesale price. Which file I have to modify and what changes I have to do?

I think that I have to customize AdminProductControllers.php, but don't know what lines to add and where exactly. Please, help me, thank you a lot.
