I am trying to associate events with entire columns in a table, but its not working (with both ‘colgroup’ or ‘col’). If it should/can work, how?

<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01//EN”
“http://www.w3.org/TR/html4/strict.dtd“>
<html lang=”en”>
<head>
</head>

<body>
<div >
<table width=”50%”>
<colgroup span=”1″ onmouseover=”javascript:alert(‘SDF’)” />

<tr>
<td> Home1 </td>
</tr>

<tr>
<td> Home2 </td>
</tr>

</table>
</div>
</body>
</html>

@FangMay 06.2007 — It should, but support for colgroup/col is patchy in all browsers.

Incidentally the minimized tag syntax is not permitted:Start tag: required, End tag: optional

A JavaScript solution:&lt;script type="text/javascript"&gt;
window.onload=function() {
var aTR=document.getElementById('table1').getElementsByTagName('tr');
for(var i=0; i&lt;aTR.length; i++) {
if (aTR[i].cells[0].addEventListener) { // W3C
aTR[i].cells[0].addEventListener('mouseover', function() {alert('SDF'); }, false);
}
else {
aTR[i].cells[0].attachEvent('onmouseover', function() {alert('SDF'); } );
}
}
}
&lt;/script&gt;

@WebJoelMay 06.2007 — I don't understand what you're trying to do, but here's something to look at:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

"http://www.w3.org/TR/html4/strict.dtd">

<html lang="en">

<head>

</head>

<body>

<div >

<table width="50%" border="1">

<tr>

<th width="50%" span="first onmouseover="javascript:alert('SDF')">First</th>

<th width="50%" span="second" onmouseover="javascript:alert('SDF-2')">Second</th></tr>

<tr>

<td> Home1 </td>

<td> Home2 </td>

</tr>

<tr>

<td> Home3 </td>

<td> Home4 </td>

</tr>


</table>

</div>

</body>

</html>[/QUOTE]
