Hi,
thanks for your post, and sorry for the trouble.
The question here is more philosophical: What do you want the table to do on small screens?
For tables with data in it, one idea is to flip it around, as e.g. possible with the TablePress Extension from http://tablepress.org/extensions/responsive-tables/
For your table, that approach is not really suitable. Instead, you could tell the images to shrink. For that, please try adding this "Custom CSS":
.tablepress-id-1 img {
max-width: 100%;
}
Regards,
Tobias
