Comment (by afercia):

 > The JS does not require the attribute to be present

 Actually the `colSpanChange()` function accepts a parameter which is the
 number to add to the colspan attribute, if present. It does check for the
 presence of a colspan attribute in the markup:

 {{{
 colSpanChange : function(diff) {
         var $t = $('table').find('.colspanchange'), n;
         if ( !$t.length )
                 return;
         n = parseInt( $t.attr('colspan'), 10 ) + diff; <-- check for the
 table colspan attribute and adds the passed param
         $t.attr('colspan', n.toString()); <-- finally, updates the colspan
 attribute with the new value
 }
 }}}
