How to disable table like rendering of gist?

[aakashnand]

I am using GitHub gist and it's rendering like the following.

How do display the gist like this without lines in between?

When inspecting through inspect tools in the browser, I found out that when I disable border-style: solid it removes the lines.
and this style is coming from

blowfish/assets/css/compiled/main.css

Line 31 in ddf79f4

border-style: solid;

Is there any way to disable the border for the GitHub gist?

Same thing also disturbed me, and since we can override theme's css with our custom, adding a file named assets/css/custom.css with following in it solves this:

.gist .highlight-wrapper tr {
    border-style: none;
}
