HTML Table Headers
Table headers are defined with th elements. Each th element represents a table cell.
Example
<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>
</tr>
<tr>
<td>Jill</td>
<td>Smith</td>
<td>50</td>
</tr>
<tr>
<td>Eve</td>
<td>Jackson</td>
<td>94</td>
</tr>
</table>
Vertical Table Headers
To use the first column as table headers, define the first cell in each row as a <th> element:
Example
<table>
<tr>
<th>Firstname</th>
<td>Jill</td>
<td>Eve</td>
</tr>
<tr>
<th>Lastname</th>
<td>Smith</td>
<td>Jackson</td>
</tr>
<tr>
<th>Age</th>
<td>94</td>
<td>50</td>
</tr>
</table>
Align Table Headers
By default, table headers are bold and centered:
| Firstname | Lastname | Age |
|---|---|---|
| Jill | Smith | 50 |
| Eve | Jackson | 94 |
To left-align the table headers, use the CSS text-align property:
Example
th {
text-align: left;
}
Header for Multiple Columns
You can have a header that spans over two or more columns.
| Name | Age | |
|---|---|---|
| Jill | Smith | 50 |
| Eve | Jackson | 94 |
To do this, use the colspan attribute on the <th> element:
Example
<table>
<tr>
<th colspan=”2″>Name</th>
<th>Age</th>
</tr>
<tr>
<td>Jill</td>
<td>Smith</td>
<td>50</td>
</tr>
<tr>
<td>Eve</td>
<td>Jackson</td>
<td>94</td>
</tr>
</table>
Table Caption
You can add a caption that serves as a heading for the entire table.
| Month | Savings |
|---|---|
| January | $100 |
| February | $50 |
To add a caption to a table, use the <caption> tag:
Example
<table style=”width:100%”>
<caption>Monthly savings</caption>
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>January</td>
<td>$100</td>
</tr>
<tr>
<td>February</td>
<td>$50</td>
</tr>
</table>
Note: The <caption> tag should be inserted immediately after the <table> tag.
