How to add filters ?

[Matt75]

I add a column for Brand name.

Display is ok.

Sorting is ok.

Now I would like to add a filter for this column, I try to add the filter in ps_admin_filter table but seem not the only things to do.

I'm will going deeper in code, I will feedback if I found a way 🤓

I would like to show difference between 1.6 and 1.7 on this page.

For 1.6 : https://github.com/Matt75/displayproductmanufacturer
For 1.7 : https://github.com/Matt75/displayproductmanufacturer/tree/1.7
