The rules Attribute

The rules attribute is used to indicate which inner borders of the table should be displayed.

rules="ruleType"

The following table shows the possible values for the rules attribute:

Value Purpose
none No inner borders (the default)
groups Displays inner borders between all table groups (groups are created by the
<thead> , <tbody> , <tfoot> , and <colgroup> elements)
rows Displays horizontal borders between each row
cols Displays vertical borders between each column
all Displays horizontal and vertical borders between each row and column

Support for this attribute is not perfect, and it has been deprecated in favor of the CSS border property, which achieves better results.

The summary Attribute

The summary attribute is used to provide additional information about the <table> element. Unfortunately, this element is not allowed in HTML5. So, how can we provide this additional summary information? The simplest solution is to provide the additonal information directly above or below the table element.


<table summary="Summary describing Rainfall in Eastern Australia">
<thead>
<tr>
  <th>&nbsp;</th>
  <th>Sydney</th>
  <th>Canberra</th>
</tr>
</thead>
<tbody>
  <tr>
	<th>January</th>
		<td>18mm</td>
		<td>20mm</td>
  </tr>
  <tr>
  <th>February</th>
	  <td>7mm</td>
	  <td>9mm</td>
  </tr>
</tbody>
