Here is a basic table structure with rows and columns:
| Header 1 | Header 2 | Header 3 |
|---|---|---|
| Data 1 | Data 2 | Data 3 |
| Data 4 | Data 5 | Data 6 |
<table>
<tr>
<th>Header 1</th>
<th>Header 2</th>
<th>Header 3</th>
</tr>
<tr>
<td>Data 1</td>
<td>Data 2</td>
<td>Data 3</td>
</tr>
<tr>
<td>Data 4</td>
<td>Data 5</td>
<td>Data 6</td>
</tr>
</table>
<thead>, <tbody>, and <tfoot>Grouping table sections allows for better organization and easier styling:
| Header 1 | Header 2 | Header 3 |
|---|---|---|
| Data 1 | Data 2 | Data 3 |
| Data 4 | Data 5 | Data 6 |
| Footer Information | ||
<table>
<thead>
<tr>
<th>Header 1</th>
<th>Header 2</th>
<th>Header 3</th>
</tr>
</thead>
<tbody>
<tr>
<td>Data 1</td>
<td>Data 2</td>
<td>Data 3</td>
</tr>
<tr>
<td>Data 4</td>
<td>Data 5</td>
<td>Data 6</td>
</tr>
</tbody>
<tfoot>
<tr>
<td colspan="3">Footer Information</td>
</tr>
</tfoot>
</table>
colspan and rowspan for Merging CellsUse colspan and rowspan to merge multiple rows or columns:
| Header Spanning 2 Columns | |
|---|---|
| Data spanning 2 rows | Data 1 |
| Data 2 | |
<table border="1">
<tr>
<th colspan="2">Header Spanning 2 Columns</th>
</tr>
<tr>
<td rowspan="2">Data spanning 2 rows</td>
<td>Data 1</td>
</tr>
<tr>
<td>Data 2</td>
</tr>
</table>
CSS can be used to style the table to improve readability:
| Header 1 | Header 2 |
|---|---|
| Data 1 | Data 2 |
<table>
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>Data 1</td>
<td>Data 2</td>
</tr>
</table>
Always use <caption> and scope for accessibility:
| Header 1 | Header 2 |
|---|---|
| Data 1 | Data 2 |
<table>
<caption>Sample Table with Data</caption>
<tr>
<th scope="col">Header 1</th>
<th scope="col">Header 2</th>
</tr>
<tr>
<td>Data 1</td>
<td>Data 2</td>
</tr>
</table>
For responsiveness, wrap the table in a container with overflow:
| Header 1 | Header 2 |
|---|---|
| Data 1 | Data 2 |
Here are a few important things to consider when using tables:
