HTML Comparison Table with Shared Product Features

A product comparison grid puts shared features on one axis and products on the other. Real header cells help visitors keep those relationships straight. Before writing the code, picture the information as a small grid. Each label should help a reader understand the value next to it.

What You Need to Know

Choose objective values where possible, such as storage or weight, and keep units consistent across products.

Read a table like a story about data. The caption says what you are looking at; row and column headers explain what the numbers or words mean.

Example: See It in Action

Take a look at this small piece of HTML. You can use it in a practice document and change the text to make it your own.

This is a short HTML fragment. To try it as a webpage, put it inside the body element of a complete HTML document.

<table>
    <caption>Phone comparison</caption>
    <thead>
        <tr>
            <th scope="col">Feature</th>
            <th scope="col">Basic</th>
            <th scope="col">Plus</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <th scope="row">Storage</th>
            <td>64 GB</td>
            <td>128 GB</td>
        </tr>
    </tbody>
</table>

Let’s Understand the Example

• Table represents information whose row and column relationships matter.
• Caption gives the whole data table a clear name.
• Scope explains which table row, column or group a th cell labels.

Look at a data cell and ask: “What row and column does this value belong to?” The header elements help answer that question, including for people who navigate the table with a screen reader.

What Should You See?

You should see a grid for “Phone comparison”, with headers such as “Feature”, “Basic”, “Plus”. The browser displays cells, but meaningful table markup also helps readers connect each cell to its labels.

Read the first data row aloud together with its column labels. If you cannot explain a value without pointing to its position on screen, strengthen the headers.

Try It Yourself

1. Add a Battery row and compare the two models using the same unit.
2. Save your changes, open or refresh the page, and compare the result with the original example.
3. Tell a friend what your change did. If you are not sure, undo it, refresh the page, and compare.

Common Beginner Mistakes

• Comparing storage as 64 GB in one column and 0.128 TB in another without explanation.
• Do not replace actual header cells with bold ordinary cells. Header markup is part of the meaning, not just the appearance.

Key Takeaways

• A product comparison grid puts shared features on one axis and products on the other.
• Table represents information whose row and column relationships matter.
• Choose objective values where possible, such as storage or weight, and keep units consistent across products.
