Delete columns topics and messages on phpBB3

I was looking at this tutorial (https://help.forumotion.com/t81777-deleting-columns-topics-and-messages) and I was wondering how would I achieve this on phpBB3?

Also, would it be possible to remove the last topic column as well?

I'm guessing it would be some sort of javascript?

Add this to adminpanel - design - colors - css tab:

Code:

dd.posts, dd.topics, dd.views, dd.lastpost {
display: none !important;
}

Thank you! That worked! Solved.
