Responsive Table Not Working - css

Question

I have created a table program in which everything works fine, but when I try to make it responsive using media queries it doesn't seem to work as you can see it is uneven. Here is the CodePen for the whole code: http://codepen.io/meeksmadness/pen/YNwOoE. I have provided some images to help if you need them and any help is appreciated.
Regular Screen:
Responsive Screen:
table {
position:relative;
z-index:0;
overflow:hidden;
border:1px solid black;
border-radius:5px;
border-collapse: collapse;
display:block;

width:100%;
margin:0 auto;
margin-top:50px;
background-color:white;
-webkit-box-shadow: 10px 10px 15px -7px rgba(0,0,0,0.60);
