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.
