Scrolling table with fixed headers at the top

I'm trying to make a table where the apad doesn't scroll, but yours does. I use percentages and a fixed width to determine how large each cell is, I want my percentage td to be the same size and aligned with thead headers.

I also have a JSFiddle to show the problem.

.main-wrapper {
  overflow-y: scroll;
  height: 300px;
  border: 1px solid blue;
}

.content-wrapper {
  height: 500px;
}

.table {
  width: 100%;
  table-layout: fixed;
}

.table.content {
  margin-bottom: 15px;
}

.header {
  position: fixed;
}

.cell {
  border: 1px solid red;
  width: 100%;
  height: 15px;
}

.medium {
  width: 100px;
}

.small {
  width: 50px;
}
<div class="main-wrapper">
  <div class="content-wrapper">
    <table class="table header">
      <thead>
        <tr>

If I delete position: fixed, it works the way I want, but the thread does not stay at the top.

I think this is not possible with CSS alone.

I tried this too long and was looking for a solution with no luck.
