Cannot hide table borders

[autotech44]

I want a table with no borders. I've tried many suggestions including:

table {

border: none;

}

and

table {

border-collapse: collapse;

}

Both hide the table borders including between columns. But there always remains and a second outer border that I can't get rid of.

Anyone else have this problem? I'm using Craft theme. The problem occurs adding tables in both products and blog posts.

What was the problem?

No thank you

Sorry. I believe someone was posting who shouldn't have been here. 

I was wondering if not using the CSS in the appropriate file is my problem. I've been using the Custom CSS on the blog post page.
