You don't need to create own column Class. You can create simple raw-column and show there anything you want:

[
    'attribute' => 'some_title',
    'format' => 'raw',
    'value' => function ($model) {                      
            return '
'.$model->id.' and other html-code
';
    },
],

This function

function ($model) {                      
    return '
'.$model->id.' and other html-code
';
}

names callback function. There is core method evaluateExpression in CComponent:

public function evaluateExpression($_expression_,$_data_=array())
{
    if(is_string($_expression_))
    {
        extract($_data_);
        return eval('return '.$_expression_.';');
    }
    else
    {
        $_data_[]=$this;
        return call_user_func_array($_expression_, $_data_);
    }
}

in our case expression is not string, it's a function, so it runs php method call_user_func_array and pass into it your model.
