Column width in list view

Hello,
I just deal with one already posted about, but for which no complete answers. As usual.

In the list view (QUOTATION DOCTYPE) in which file can I change the colwidth columns so as to add another column.

What file (full path please) can I change this?

If you do not have the answer or you want to retain information, do not reply please.

You can edit the doctype and check “In list view” for the respective field you want to show in list view.

I know. My question is how to change the column width

This is the file where the column width is applied using Bootstrap classes
