Width of columns in stock central

Good morning,
I was wondering if it was possible to change the width of the columns as the full name is not visible, and in the case of names with similar prefix it is not obvious at a glance which is the correct product.
There is a lot of wasted space between the columns without any useful information.
I know there is a procedure via theme editing but it is not applicable in my case since, using Oxygen Builder, themes are disabled.
