Second page link: How to Auto-Wrap Only Large Tables (Based on Column Count) Using jQuery
Awesome!
Let's take it to the next level and add a "Scroll to view" label automatically above wide tables!
This helps users instantly know that the table is scrollable — which is great for user experience, especially on mobile or small screens.
Step-by-Step Plan:
-
Select all tables on the page.
-
Check the number of columns.
-
For wide tables, first insert a label ("Scroll to view") above the table.
-
Then wrap the table with a div for scrolling.
✅ jQuery Code
$(document).ready(function(){
$("table").each(function(){
var columnCount = $(this).find('tr:first-child td, tr:first-child th').length;
if (columnCount > 5) {
// Check if already wrapped
if (!$(this).parent().hasClass('table-wrapper')) {
// Add scroll notice
$(this).before('<div class="scroll-notice">Scroll to view</div>');
// Wrap the table
$(this).wrap("<div class='table-wrapper'></div>");
}
}
});
});
Explanation
-
$(this).before()→ Inserts an element before the table. -
<div class="scroll-notice">Scroll to view</div>→ This is the small notice telling users to scroll. -
.wrap("<div class='table-wrapper'></div>")→ Wraps the table inside a scrollable div.
Now your wide tables will look smarter and guide users!

<title>Auto-Wrap and Add Scroll Notice to Large Tables</title>
<style>
.table-wrapper {
overflow-x: auto;
max-width: 100%;

<h2>Small Table (No Notice)</h2>
<table>
<tr><th>Name</th><th>Age</th><th>City</th></tr>
<tr><td>John</td><td>25</td><td>New York</td></tr>
<tr><td>Jane</td><td>30</td><td>Los Angeles</td></tr>
</table>
<h2>Large Table (Notice + Scroll)</h2>
<table>

<th>Product</th><th>Price</th><th>Stock</th><th>SKU</th><th>Category</th><th>Brand</th>
</tr>
<tr>
<td>Phone</td><td>$699</td><td>Available</td><td>PH1234</td><td>Electronics</td><td>Samsung</td>
</tr>
<tr>
<td>Laptop</td><td>$999</td><td>Available</td><td>LT5678</td><td>Electronics</td><td>Dell</td>
</tr>
</table>
<script>
$(document).ready(function(){
$("table").each(function(){
var columnCount = $(this).find('tr:first-child td, tr:first-child th').length;
if (columnCount > 5) {
if (!$(this).parent().hasClass('table-wrapper')) {
$(this).before('<div class="scroll-notice">Scroll to view</div>');
$(this).wrap("<div class='table-wrapper'></div>");
}
}
});
});
</script>
</body>
</html>
Pro Tips:
-
Style the notice differently:
You can make it bolder, colorful, or even use an icon for better UX. -
Make the message dynamic:
Instead of always "Scroll to view", you could even detect if it's a mobile screen and change the message like "Swipe to scroll" for touch devices. -
Use smooth animation:
If you want, you can add a little animation to the notice (like fading in) with.fadeIn()or.slideDown()in jQuery.
Common Pitfalls to Avoid
-
Duplicate notices:
If your script runs multiple times, make sure you don't add multiple notices by mistake. You can check if a.scroll-noticealready exists. -
Wrong column counting:
Always target both<td>and<th>in your selector. -
Performance on Huge Pages:
If you have hundreds of tables, try to optimize the code by selecting tables in specific containers rather than scanning the whole page.
Conclusion
By combining dynamic wrapping and scroll notifications, you not only make your tables responsive but also guide users perfectly — boosting the overall usability of your site!
This small trick can seriously upgrade your tables without touching much backend code at all.
See an even more advanced version where the "Scroll to view" notice only appears when the table actually overflows horizontally (even on window resize)?
That would make it super professional!
