Remove columns in show-league.php

Follow this topic https://ww.wp.xz.cn/support/topic/extra-column-in-matches-table I was able to add new headers and columns. But I can’t figure out how to remove columns. I don’t want Overtime, Halftime and Penalty options. How can I remove it?

Thanks in advance.
