The AJAX-based validation has a few limitations. First, it does not work with file upload fields. Second, it should not be used to perform validations that may cause server-side state changes. Third, it is not designed to work with tabular data input for the moment.

So, you need to write custom error handler for tabular data

//view
$form = $this->beginWidget('CActiveForm', array(   
    'enableClientValidation' => true,
    'clientOptions' => array(
        'validateOnChange' => false,
        'validateOnType' => false,
        'validateOnSubmit' => true,
        'beforeValidate' => 'js:formBeforeValidate',
        'afterValidate' => 'js:formAfterValidate'
    ),
));
//some js
function formBeforeValidate (form) {    
    //clean errors
    return true;
}

function formAfterValidate(form, data, hasError) {    
    if (hasError === true) {
        //append errors to input
    }
    return !hasError;
}
