[Theme: Arcade] Table not viewable in mobile

Hello guys. I’m used the Arcade theme to make my site. When I try to view my site on my iPhone, I can’t view the table on this page: https://myhj3313.dothome.co.kr/?p=365

It goes beyond the resolution.

Also, when I use my iPhone to view my site: https://myhj3313.dothome.co.kr/ it doesn’t open at the “exact” fit of my iPhone screen. I need to zoom out a little for it to fit the screen properly. What should I add on my css file? Because I know that iPhone’s resolution is a little different from the others. I hope you can help me. Thanks! ??
