Custom additional column in catalog products page

[viperman022]

Hi all,

 

I'd like to display an additional column in the back office 'Product' page to be exact on catalog->products page where all products are shown. Next to product name preferably, I'd like to display an custom field with corresponding value from my module which uses an db table.

 

Maybe someone could help me on what to do? I did try to override 'Controllers/Admin/AdminProductsController.php' via adding it to my module also did try deleting 'cache/class_index.php' but it seems either i cant override __construct() function or i am overriding wrong file...
