Column Width Responsive Issue

From reading other threads, it seems that the issue stems from the width of non-breaking content in some cells.

I’d like all columns to mirror/equal the width of the widest column if possible. What’s most important is that the CTA responsive buttons are a uniform size.

Scroll was part of the plan so wider than page tables are no problem.

I’ve tried different widths in % and pixel, but I’m running in circles at this point. Hoping that a solution to this table will translate to others on the site with the same issue.

This is what I’ve currently inserted to the custom css under ‘Plugin Options’:
.tablepress-id-40 .column-2,
.tablepress-id-40 .column-3,
.tablepress-id-40 .column-4,
.tablepress-id-40 .column-5,
.tablepress-id-40 .column-6 {
width: 20%;
}

Big fan of the plugin, thanks in advance.
