Try something like this:

//In your head:

<script type="text/javascript">
var myRenderer = function(value, metadata, record) {
    return record.get('FirstName') + ' ' + record.get('LastName');
}
</script>


<ext:Column ColumnID="Name" Sortable="false" Resizable="false" MenuDisabled="true">
    <Renderer Fn="myRenderer" />
</ext:Column>
