Defining HTML Tables

Example

<table style=”width:100%”>
<tr>
<td>Jill</td>
<td>Smith</td>
<td>50</td>
</tr>
<tr>
<td>Eve</td>
<td>Jackson</td>
<td>94</td>
</tr>
</table>

Tables are defined with the <table> tag.
Tables are divided into table rows with the <tr> tag.
Table rows are divided into table data with the <td> tag.
A table row can also be divided into table headings with the <th> tag.

An HTML Table with a Border Attribute

If you do not specify a border for the table, it will be displayed without borders.
A border can be added using the border attribute:

Example

<table border=”1″ style=”width:100%”>
<tr>
<td>Jill</td>
<td>Smith</td>
<td>50</td>
</tr>
<tr>
<td>Eve</td>
<td>Jackson</td>
<td>94</td>
</tr>
</table>
To add borders, use the CSS border property:

Example

table, th, td {
border: 1px solid black;
}
If you want the borders to collapse into one border, add CSS border-collapse:

Example

table, th, td {
border: 1px solid black;
border-collapse: collapse;
}

If you want the borders to collapse into one border, add CSS border-collapse:

Example

table, th, td {
border: 1px solid black;
border-collapse: collapse;
}

HTML Table Headings

Table headings are defined with the <th> tag.
By default, all major browsers display table headings as bold and centered:

Example

<table style=”width:100%”>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Points</th>
</tr>
<tr>
<td>Eve</td>
<td>Jackson</td>
<td>94</td>
</tr>
</table>

Table Cells that Span Many Columns

To make a cell span more than one column, use the colspan attribute:

Example

<table style=”width:100%”>
<tr>
<th>Name</th>
<th colspan=”2″>Telephone</th>
</tr>
<tr>
<td>Bill Gates</td>
<td>555 77 854</td>
<td>555 77 855</td>
</tr>
</table>

An HTML Table With a Caption

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>
