A Simple Guide to Creating Responsive HTML Tables

In modern web development, responsive HTML tables are crucial for maintaining usability across different screen sizes. Tables often present challenges on smaller screens due to their rigid structure. This guide covers multiple techniques to make HTML tables responsive, including horizontal scrolling, column hiding, row collapsing, and advanced layout strategies using Flexbox and Grid. Each method includes practical examples to help you implement them effectively.

Why Responsive Tables Matter

Tables are commonly used for displaying structured data like pricing plans, schedules, or comparisons. On mobile devices, tables can become difficult to read or navigate. A responsive table adapts to the screen size, preserving readability and improving user experience.

1. Horizontal Scrolling with CSS Overflow

The simplest responsive table technique is wrapping the table in a container with overflow-x: auto, allowing horizontal scrolling.

CSS

12345678
.table-container {
  overflow-x: auto;
  max-width: 100%;
}
.table-container table {
  width: max-content;
  border-collapse: collapse;
}

HTML

1234567891011121314151617181920212223242526
<div class="table-container">
  <table>
    <thead>
      <tr>
        <th>Name</th>
        <th>Age</th>
        <th>Occupation</th>
        <th>Location</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>Ravi Sankar</td>
        <td>30</td>
        <td>Developer</td>
        <td>India</td>
      </tr>
      <tr>
        <td>Jane Smith</td>
        <td>25</td>
        <td>Designer</td>
        <td>US</td>
      </tr>
    </tbody>
  </table>
</div>

Pros

• Simple to implement
• Retains full table structure
• Suitable for wide tables

Cons

• Horizontal scroll may affect usability
• Doesn’t restructure content

2. Hiding Columns on Smaller Screens

Use CSS media queries to hide less-important columns on small screens.

CSS

12345
@media screen and (max-width: 600px) {
  .hide-on-mobile {
    display: none;
  }
}

HTML

123456789101112131415161718192021222324
<table>
  <thead>
    <tr>
      <th>Name</th>
      <th>Age</th>
      <th class="hide-on-mobile">Occupation</th>
      <th class="hide-on-mobile">Location</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Ravi Sankar</td>
      <td>30</td>
      <td class="hide-on-mobile">Developer</td>
      <td class="hide-on-mobile">India</td>
    </tr>
    <tr>
      <td>Jane Smith</td>
      <td>25</td>
      <td class="hide-on-mobile">Designer</td>
      <td class="hide-on-mobile">US</td>
    </tr>
  </tbody>
</table>

Pros

• Removes clutter on small screens
• Maintains basic structure

Cons

• Information loss if hidden columns are important

3. Collapsing Rows into Stacked Cards

Transform rows into card-style blocks using display: block and data-label attributes.

CSS

12345678910111213141516171819202122232425
@media screen and (max-width: 600px) {
  table, thead, tbody, th, td, tr {
    display: block;
  }
  thead {
    display: none;
  }
  tr {
    margin-bottom: 15px;
    border: 1px solid #ddd;
    padding: 10px;
  }
  td {
    position: relative;
    padding-left: 50%;
    text-align: left;
  }
  td:before {
    content: attr(data-label);
    position: absolute;
    left: 10px;
    width: 45%;
    font-weight: bold;
  }
}

HTML

123456789101112131415161718192021222324
<table>
  <thead>
    <tr>
      <th>Name</th>
      <th>Age</th>
      <th>Occupation</th>
      <th>Location</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td data-label="Name">Ravi Sankar</td>
      <td data-label="Age">30</td>
      <td data-label="Occupation">Developer</td>
      <td data-label="Location">India</td>
    </tr>
    <tr>
      <td data-label="Name">Jane Smith</td>
      <td data-label="Age">25</td>
      <td data-label="Occupation">Designer</td>
      <td data-label="Location">US</td>
    </tr>
  </tbody>
</table>

Pros

• Mobile-friendly
• Clear content structure

Cons

• Requires data-label attributes

4. Flexbox for Wrapping Cells

Flexbox can wrap cells dynamically within a responsive container.

CSS

1234567891011121314151617
.table-container {
  display: flex;
  flex-wrap: wrap;
}
table {
  flex: 1 1 100%;
}
th, td {
  flex: 1 1 25%;
  padding: 10px;
  border: 1px solid #ddd;
}
@media screen and (max-width: 600px) {
  th, td {
    flex: 1 1 50%;
  }
}

Pros

• Responsive and flexible
• All content remains visible

Cons

• Less control over exact dimensions

5. Collapsible Rows with JavaScript

Toggle visibility of row details with buttons and JS.

          <p>Location: US</p>
        </div>
      </td>
    </tr>
  </tbody>
</table>

<script>
function toggleDetails(button) {
  const details = button.nextElementSibling;
  const isHidden = details.style.display === 'none';
  details.style.display = isHidden ? 'block' : 'none';
  button.textContent = isHidden ? 'Hide Details' : 'Show Details';
}
</script>

CSS

1234

table {
  display: contents;
}
th, td {
  border: 1px solid #ddd;
  padding: 10px;
}

Pros
