Layout issues

I’m creating a “media” page where I will post an image, which links to a video. I want 3 images per line and I want to be able to sort them by date and keep the layout nice and clean. The only way I thought to do this (I have very little coding experience) was to add a table, throw the images into the table and sort it like that.

I’ve started doing this but the table border isn’t invisible like I wanted! How can I change this or do you know a better way to achieve this type of organization?

That’s the page in question.
