HTML Table
- HTML provides tables as a tool for organizing and displaying data in rows and columns.
- Tables are essential for presenting structured information in a tabular format.
- They offer flexibility in defining headers, rows, columns, and additional attributes.
- Let's explore the attributes and examples of HTML tables to understand their complete functionality.
1. Basic Table Structure:
The most common use of a table is to display data in rows and columns. Here's a basic example:
<table>
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>Data 1</td>
<td>Data 2</td>
</tr>
</table>
2. Table Headers:
You can use the <th>
element to define headers for rows or columns:
<table>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
<tr>
<td>John</td>

</tr>
</table>
3. Table Captions:
You can add a caption to the table using the <caption>
element:
<table>
<caption>List of Employees</caption>
<tr>
<th>Name</th>
<th>Position</th>
</tr>
<tr>
<td>Alice</td>
<td>Manager</td>
</tr>
</table>
4. Table Borders and Styling:
You can add borders and styles to the table using CSS:
table {
border-collapse: collapse;
}
th, td {
border: 1px solid black;
padding: 8px;
}
5. Spanning Rows and Columns:
You can span multiple rows or columns using the rowspan
and colspan
attributes:
<table>
<tr>
<td colspan="2">Header</td>
</tr>
<tr>
<td>Data 1</td>
<td rowspan="2">Data 2</td>
</tr>
<tr>
<td>Data 3</td>
</tr>
</table>
6. Table Accessibility:
Ensure your table is accessible by providing appropriate header cells and using semantic markup:
<table>
<thead>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr>
<td>John</td>
<td>30</td>
</tr>
</tbody>
</table>
7. Use Cases:

- They're commonly used in reports, dashboards, and financial statements to present structured information in a concise format.
- Tables can be employed in conjunction with JavaScript libraries or frameworks to create dynamic and interactive data tables.
- They facilitate data comparison, analysis, and visualization, enabling users to make informed decisions based on the presented information.
- Tables can be used for accessibility purposes, providing structured data for screen readers and alternative navigation options for users with disabilities.
