are you using CGridView? if so then when initiating widget
$this->widget('zii.widgets.CGridView', array(
'dataProvider'=>$dataProvider,
// add columns manualy
'columns'=>array(
// add number
array(
'name'=>'Number',
// an array of class and method wich will be called with call_user_func_array
'value'=>array('MyClass', 'myMethod')
),
'username',
'email'
)
);
//the callback function
class MyClass
{
public static function myMethod($data, $row, $component)
{
//the $data is the ActiveRecord Model collection from the dataProvider
//the $row is the data row
//the $component is the CGridColumn object for each columns
// return the result you want
}
}
