About Using FootTable

Currently, I am building a screen for my smartphone, and to make the table variable
I'm trying to use Footable.
I refer to the following site.

http://www.webantena.net/javascriptjquery/plugin-footable/

However, I can't get the essential sauce.
Because not only here, but also any site will eventually get
from Github. You are prompted to download it, but the source cannot be found.

Above all, it says that the image of the opening and closing button comes with it, but
There's nothing like that.

Is it no longer available?
