CSS - 粘性表头

Question

我这里有一个代码笔 - Code

这是一个容器中的表，该表比容器大。

从左向右滚动表格时，标题移动

当向上和向下滚动时，我需要标题是粘性的，并且内容要在下面移动。

它在这里有用 - Code

但是我丢失了列和表格的宽度。

如何使标题粘性但保持表格的宽度

body{
  background: grey;
  font-family: sans-serif;
}
.page{
  background: white;
  width: 1200px;
  margin: 0 auto;
}
.table-con{
  overflow: scroll;
  max-width: 1200px;
  height: 500px;
} 

table{
  /*table-layout: fixed;*/
  border-collapse: collapse; 
  width: 1500px;
}

thead th:first-child{
  width: 20px;
  padding: 0;
}

thead th{
  text-align: left;
}

thead tr{
  border-bottom: 1px solid #444;
}

tbody td{
  border-bottom: 1px solid #aaa;
}

tbody tr:nth-child(even) td:not(:first-child){
  background: yellow;
}

tbody td:first-child{
  background: none;
  border: none;
  padding: 0;
}

th, td{
  padding: 10px 5px;

   &:first-of-type{
    padding-left: 20px;
  }

  &:last-of-type{
    padding-right: 20px;
  }
}
