Responsive table, unable to line up thead and tbody - html

Question

I have created a table however I cannot get the <thead>s to line up with the <tbody>s.
The table is responsive and works as I want it to when resized, however it's the initial screen size that is the issue.
I have added float:left to the <thead>s so they align properly instead of overlapping each other and would like the table data to a-line in the same way.
table {
border: 1px solid #ccc;
border-collapse: collapse;
margin: 0;
padding: 0;
width: 100%;
table-layout: fixed;
}
table caption {
font-size: 1.5em;
margin: .5em 0 .75em;
}
table tr {
background: #f8f8f8;
border: 1px solid #ddd;
padding: .35em;
}
table th,
table td {
padding: .625em;
text-align: center;
}
table td {
font-size: 0.60em;
}
table th {
font-size: .60em;
letter-spacing: .1em;
text-transform: uppercase;
}
#media screen and (max-width: 600px) {
table {
border: 0;
}
table caption {
font-size: 1.3em;
}
table thead {
border: none;
clip: rect(0 0 0 0);
height: 1px;
margin: -1px;
overflow: hidden;
padding: 0;
position: absolute;
width: 1px;
}
table tr {
border-bottom: 3px solid #ddd;
display: block;
margin-bottom: .625em;

table td {

text-align: right;
}
table td:before {
/*

content: attr(aria-label);

content: attr(data-label);
float: left;

Answer 1

Instead of using float:left for thead just change
table {
table-layout: fixed;
}
to
table {
table-layout: auto;
}
