Spservices autocomplete with many columns

Could somebody advise how can I make autocomplete for multiple columns, currently I’m using it for one column:

$  ().SPServices.SPAutocomplete({     sourceList: "My list",     sourceColumn: "Email",     columnName: "user1",     ignoreCase: true,     numChars: 3,     slideDownSpeed: 1000,     debug: true }); 

Can I do something like this:

... columnName: "user1", "user2", "user3"... etc. ... 

UPDATE:

My form and JavaScript looks like this:

<div class="tr">   <div class="td">     <input title="user1" data-bind="textInput: user1Email, valueUpdate:'blur'" />   </div> </div> <div class="tr">   <div class="td">     <input title="user2" data-bind="textInput: user2Email, valueUpdate:'blur'" />   </div> </div>  <script type="text/javascript"> $  (document).ready(function () {     $  (["user1", "user2", "user3"]).each(function () {         $  ().SPServices.SPAutocomplete({             sourceList: "User List",             sourceColumn: "Email",             columnName: this,             ignoreCase: true,             numChars: 3,             slideDownSpeed: 1000,             debug: true         });     }) }); </script>
