Creating Scrollable HTML Table with Fixed Headers and First Column
How do you create an HTML table with fixed column headers and a first column that remains visible while scrolling the table's contents?
Answer:
To achieve this effect, you can utilize a combination of CSS and JavaScript. Here's how you can do it:
1. Create an HTML Table:
<code class="html"><table> <thead> <tr> <th>Column 1 Header</th> <th>Column 2 Header</th> <th>Column 3 Header</th> </tr> </thead> <tbody> <tr> <td>Data 1</td> <td>Data 2</td> <td>Data 3</td> </tr> <!-- more table rows --> </tbody> </table></code>
2. CSS for Fixed Headers and First Column:
<code class="css">table { width: 100%; overflow: scroll; } table thead { position: sticky; top: 0; } table tr td:first-child { position: sticky; left: 0; }</code>
This CSS ensures that the table headers are fixed to the top of the screen when scrolling and that the first column remains fixed to the left.
3. Enhanced Example:
You can also use advanced CSS Grid to achieve a similar effect with better support for responsiveness and screen readers:
<code class="css">table { display: grid; grid-template-columns: repeat(3, auto); grid-template-rows: auto 1fr; } table thead { grid-row: 1; grid-column: 1 / -1; } table tr { grid-column: 1 / -1; } table tr td:first-child { grid-column: 1; } table tbody { overflow: scroll; }</code>
Note: The provided examples may require some adjustments depending on your specific table design and browser compatibility requirements.
