Currently, I am dealing with a vast amount of data presented in a table format with numerous rows and columns. To manage this, I have opted to enclose the table within an overflow:scroll div. However, I am seeking a solution that allows me to keep the first row visible even when scrolling down.
I am wondering if there is a way to achieve this functionality using pure HTML, or if there are any clever tricks like utilizing JavaScript?
I'm assuming you're looking for something similar to this setup?

You don't really need JavaScript for this. You can just use position: absolute to place the contents of a div inside each th.
For example:
CSS
th div {
position: absolute;
background: transparent;
color: #fff;
padding: 9px 25px;
top: 0;
margin-left: -25px;
line-height: normal;
border-left: 1px solid #800;
}
HTML
<table>
<thead>
<tr class="header">
<th>
Table attribute name
<div>Table attribute name</div>
</th>
<th>
Value
<div>Value</div>
</th>
<th>
Description
<div>Description</div>
</th>
</tr>
</thead>
<!-- ...etc... -->
PS: There are better ways to achieve this, but the example above is taken from an existing JSFiddle.
Take a look at jQuery.floatThead (you can see demos there) - it's really impressive! It has compatibility with DataTables and can function seamlessly within an overflow: auto container.
To keep the first row constantly visible, you can apply the CSS property position:fixed and set it to appear at the top of the corresponding div using top:0. By doing this, the other columns will overlap with the fixed column. To prevent this overlap, ensure that your scrollable div has a padding-top value equivalent to the height of the fixed column.
