How can I make my table sections wider in Spark theme?

Hi,

What should I do to make the sections in my table wider? The first picture shows how it looks now. The third picture shows how I want it.

The table is a size guide that I put in “Information popup content” in the “variant sectors” section. The second picture shows how and where I made the table. The fourth image shows some of the code.

I am using the theme Spark and my website is arcaneattire.com
