How do I link two rows in HTML?

To "link" two rows in HTML, you're likely asking about merging table rows. You can achieve this using the rowspan attribute within the <td> or <th> tags. This attribute specifies the number of rows a cell should span.

Using the rowspan Attribute

The rowspan attribute is used to make a table cell span multiple rows.

<table>
  <tr>
    <th>Header 1</th>
    <th>Header 2</th>
  </tr>
  <tr>
    <td rowspan="2">Cell that spans two rows</td>
    <td>Cell 2</td>
  </tr>
  <tr>
    <td>Cell 3</td>
  </tr>
</table>

In this example, the first cell in the second row (<td>Cell that spans two rows</td>) spans two rows because rowspan is set to "2". This effectively merges the first cell of the second and third rows.

Explanation:

• <table>: Defines the HTML table.
• <tr>: Defines a table row.
• <th>: Defines a table header cell.
• <td>: Defines a standard table data cell.
• rowspan="2": This attribute, when placed inside a <td> or <th> tag, makes that cell span two rows vertically. You can change the number ("2") to specify a different number of rows to span.

Example: Practical Insight

Imagine creating a timetable. You might have a lecture that lasts for two hours, effectively taking up two rows in your timetable. The rowspan attribute helps represent this visually in an HTML table.

<table>
  <tr>
    <th>Time</th>
    <th>Monday</th>
  </tr>
  <tr>
    <td>9:00 - 10:00</td>
    <td rowspan="2">Lecture A</td>
  </tr>
  <tr>
    <td>10:00 - 11:00</td>
  </tr>
</table>

Here, "Lecture A" occupies the 9:00-10:00 and 10:00-11:00 time slots.

Important Considerations:

• Table Structure: Ensure your table structure is logically sound. Using rowspan effectively requires planning how the data will align.
• Accessibility: Consider accessibility when using rowspan. Screen readers may interpret complex tables with spanned rows in unexpected ways. Provide appropriate ARIA attributes if necessary to improve accessibility.
