I utilized scriptaculose/prototype Builder to create TR and TD. The colspan doesn't work in IE, but it works in FF and Chrome. Do you have any experience on this issue?

This doesn't work in IE, but it works in FF and Chrome:

`Builder.node('td',{'colspan':'12','class':'bdr-bottom'},(noteText))`

This works in IE, FF and Chrome:

```
for (var i=1; i<numCols; i++)
{       
    noteRowSpan=Builder.node('td',{'class':'bdr-bottom'},(''));     
    $(noteRow2).insert($(noteRowSpan));  
}       

```
