Fixed table header with responsive table not working

Question

I'm trying to fix my table header once it is scrolled down that it fixed at the top position.

I've managed to fix the header by making a javascript to detect the scroll position and then apply css to make the position as fixed at the top

But the column sizing of the header become lost, apparently it become smaller.

I will appreciate if someone able to help on this?

<html>

<header>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>
<style>
.scroll{
   position: fixed;
   top: 0 !important;
}

#myDIV{
   background-color: #ccc;
}

header{
   height: 100px;
}

footer{
   height: 2000px;
}
</style>
</header>
<body> 
<table style="width:1900px" >
        <thead id="myDIV">
            <tr>
                <th style="width:25%"  >Column1</th>

                <th  style="width:25%" >Column3</th>
                <th  style="width:25%" >Column4</th>
            </tr>

Always nice to explain your solution instead of just posting code.

George Wang Over a year ago

You need to set width to table and set display property with block and other width options.

Alona Over a year ago

display: block; to th elements - this is the key you can solve the problem.

If your not needed old browser you can use position: sticky. sticky is the powerful property in CSS-3 learn about position sticky link for sticky

If you need old browser support you can use jquery sticky table header cross browser

table thead,
table thead th {
  position: sticky;
  top: 0;
  background: #ccc;
}

header {
  height: 100px;
}

footer {
  height: 2000px;
}

<header>
</header>

<body>
  <table style="width:1900px">

        <th style="width:25%">Column2</th>
        <th style="width:25%">Column3</th>
        <th style="width:25%">Column4</th>
      </tr>
    </thead>
