    <style>
        table {
            width: 100%;
            border-collapse: collapse;
        }
        th, td {
            border: 1px solid black;
            padding: 8px;
            text-align: left;

        .column-chooser {
            margin-bottom: 20px;
        }
    </style>
</head>
<body>
    <div class="column-chooser">
        <label><input type="checkbox" checked data-column="name"> Name</label>
        <label><input type="checkbox" checked data-column="age"> Age</label>
        <label><input type="checkbox" checked data-column="email"> Email</label>
    </div>
    <table>
        <thead>
            <tr>
                <th class="name">Name</th>
                <th class="age">Age</th>
                <th class="email">Email</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td class="name">John Doe</td>
                <td class="age">30</td>
                <td class="email">john@example.com</td>
            </tr>
            <tr>
                <td class="name">Jane Smith</td>
                <td class="age">25</td>
                <td class="email">jane@example.com</td>
            </tr>
        </tbody>
    </table>
    <script>
        document.querySelectorAll('.column-chooser input[type="checkbox"]').forEach(checkbox => {
            checkbox.addEventListener('change', (event) => {
                const columnClass = event.target.getAttribute('data-column');
                const isChecked = event.target.checked;
                document.querySelectorAll(`.${columnClass}`).forEach(cell => {
                    cell.style.display = isChecked ? '' : 'none';
                });
            });
        });
    </script>
</body>
</html>

Explanation:

HTML Structure:
- A div with the class column-chooser contains checkboxes for each column.
- A table is defined with thead and tbody sections.
- Each column and cell have a class corresponding to the column name (name, age, email).
CSS:
- Basic styling is applied to the table and its elements for readability.
JavaScript:
- Adds an event listener to each checkbox in the column chooser.
- When a checkbox is toggled, the corresponding column cells are shown or hidden by changing their display style.

This example provides a simple, interactive way for users to choose which columns they want to display in a table. You can expand this by adding more functionality or integrating it into a larger application as needed.
