tag is used to create tables in HTML. Tables are useful for displaying data in rows and columns.

</tr>
<tr>
<td>Utilities</td>
<td>$300</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>Total</td>
<td>$1500</td>
</tr>
</tfoot>
</table>
Adding Borders and Styling
By default, tables have no borders. You can add borders and style tables using CSS.
Example: Adding Borders
<table style="border-collapse: collapse; width: 100%;">
<tr>
<th style="border: 1px solid black; padding: 8px;">Name</th>
<th style="border: 1px solid black; padding: 8px;">Age</th>
</tr>
<tr>
<td style="border: 1px solid black; padding: 8px;">Alice</td>
<td style="border: 1px solid black; padding: 8px;">30</td>
</tr>
<tr>
<td style="border: 1px solid black; padding: 8px;">Bob</td>
<td style="border: 1px solid black; padding: 8px;">25</td>
</tr>
</table>
Best Practices:
- Use
border-collapse: collapse
for consistent borders. - Add
padding
for better readability.
Merging Cells with colspan and rowspan
You can merge cells horizontally or vertically using colspan
and rowspan
.
Example: Merging Cells
<table border="1">
<tr>
<th>Category</th>
<th>Details</th>
</tr>
<tr>
<td rowspan="2">Electronics</td>
<td>Phone</td>
</tr>
<tr>
<td>Laptop</td>
</tr>
<tr>
<td colspan="2">Total: $2000</td>
</tr>
</table>
Making Tables Accessible
Accessible tables help users with screen readers understand the content.

scope
attribute in<th>
:
<th scope="col">Item</th>
<th scope="row">Cost</th>
- Add a
<caption>

<thead>
,<tbody>
, and<tfoot>

<table border="1">
<tr>
<th>Name</th>
<th>Age</th>
<th>Location</th>
</tr>
<tr>
<td>Alice</td>
