Syntax
Description
While it’s possible to set the
alignment of text at th and td
level—and alignment is well-supported for those elements—it does mean
repeating that align attribute for every
row. Applying the align to a
colgroup element avoids this overhead (or rather, it
should).
Example
This example shows the setting of
alignment in colgroup elements to
"center":
<table border="1">
<colgroup align="center">
<col/>
<col/>
<col/>
<col/>
</colgroup>
<tr>
<th colspan="4" scope="col">Work Contact Points</th>
</tr>
<tr>
<th>Name</th>
<th>Email</th>
<th>Phone</th>
<th>Floor/Block</th>
</tr>
⋮
</table>
Value
The recognized attribute values are as shown in the syntax section.

Compatibility for
align, when it’s set to
colgroup, is very poor, as the support chart shows
(this time it’s IE and Opera who are the good guys!). As such, it cannot
be relied upon, nice as the idea is.
