Block has different font

Hello,

I’m a little confused about the “Table” block option.

When I insert a table into a post, it shows up with a different font than the rest of the post. More specifically, I’m pretty sure it’s the font that this theme originally came with, even though I’ve changed that and it’s working fine on the rest of the site.

I’m assuming this is a CSS issue, but since I’m not well-versed in this at ALL I have no idea where to start.

You can see the issue in the link I’ve provided. I hope someone has an idea on how to adjust this, as it’s not very visually pleasing! My apologies if there’s an easy fix that I’m simply overlooking.

Thanks,
Mari
