Alright. I think I see what you're trying yo do. You will need to edit the size of your body table within the HTML. Set it to the maximum size you want to display. Next, you will need to edit your styled-elements.css
Code:
/* TABLE ------------------------------------------------------------*/
table, td, th {
vertical-align:middle;
}
table {
border-collapse:separate;
border-spacing:0;
border-top:1px solid white;
margin-bottom:28px;
width:100%;
text-align: left;
}
th{
border-top:5px solid #555555;
color: #ffffff;
padding:10px;
text-transform:uppercase;
background-color: #49494b;
}
td{
padding:10px;
}
td, th{
border-bottom: 1px solid #1f1f1f;
}
Thats the section you'll need to edit in the css.
