How can I shorten this, the key is the expression and the colspans:

if (counter == 1) {
<td colspan="4">&nbsp;</td>
} if (counter == 2) {
<td colspan="3">&nbsp;</td>
} if (counter == 3) {
<td colspan="2">&nbsp;</td>
} if (counter == 4) {
<td colspan="1">&nbsp;</td>
}

Is the total number of columns dynamic, or will there always be at most 4? Also, are you generating this server side or clients side? The code you supplied doesn't look like it would work for either, if you're wanting to do this client side something similar to what cvdtbrrsln posted will work. If you're wanting to do it server side, well.... we'll have to know what SSL you're using first. And whether the columns are dynamic too, and what variable the number of columns is stored in.

no... it is ss... the number of columns and options for "counters" values are set - they will be 1-4...

I'll post an example in asp (using server side JScript) using cvdtbrrsln's suggestion:
Code: 
<html>
<head>
</head>
<body>
<table border="1" cellpadding="0" cellspacing="1">
<tr><td>&nbsp;</td><td>&nbsp;</td><td>&nbsp;</td></tr>
<tr>
<%
//value from 1 to 4, I assume this is generated server side?
var counter = 1;
var colspanvalue = (5 - counter);
Response.Write("<td colspan=" + colspanvalue + ">&nbsp;</td>");
%>  
</tr>
<tr><td>&nbsp;</td><td>&nbsp;</td><td>&nbsp;</td></tr>
</table>
</body>
</html>
