Column Width

Hi,

I am using tablepress on this page: https://www.bookgeeks.in/7-best-indian-romance-novels/

I’m unable to set the width of the column with images. I’ve tried using this code
.tablepress-id-6 .column-1 {
width: 25%;
}

But when the page is viewed on mobile devices, the column-1 takes up most of the screen.

Appreciate your help.
