You can make the line-gap smaller by using
<style>
hr{
margin: 2px 0;
}
</style>
I would really recommend you to lookup some CSS-basics. When you know your CSS, you don’t really need to guess, but you’ll know which element you can style. Also, the developer tools in every browser (just press F12) will help you.
As for the ‘w’-entry, that’s where you have a point. It’s in fact the last entry in your list, so it doesn’t get a spacer (as there is no other element ‘behind’ it. I don’t have a solution to this at this moment.
However, this should do the trick (more or less).
<style>
.name_directory_column.name_directory_nr3:last-child .name_directory_name_box:last-child {
border-bottom: 1px solid lightgray;
padding-bottom: 31px;
}
</style>
