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;
}

There is no inbuilt mechanism in Yii to ajax validation for tabular data. I implemented custom validation using jquery for this purpose. Below is the code that I used to create a custom ajax validation for tabular data.

Controller: It assigns the value passed to the model attribute and returns any error for the attribute.

public function actionValidateData($value,$name)
{
    $model = new BusinessPartner;
    $model->setAttribute($name, $value);
    $model->validate();
    echo CHtml::error($model,$name);
    Yii::app()->end();
}

Jquery function to make ajax call and show the messages. I have added class 'businessPartner' to all the fields of the model.

$(document).on('blur','.businessPartner',function(e){
    e.preventDefault();
    var id= $(this).attr('id');
    var name= $(this).attr('rel');
    $.ajax({
        url:"<?php echo Yii::app()->createUrl('user/validatedata'); ?>",
        type: "GET",
        data: 'value='+$.trim($(this).val())+'&name='+ name,
        success :function(data){
            if($.trim(data))
            {   
                if(!$('#'+id).hasClass('error'))
                {
                    $('#'+id).addClass('error');
                    $('#'+id).prev().addClass('error');
                    $('#'+id).after(data);
                }
            }
            else
            {
                if(!$('#'+id).parent().hasClass('success'))
                {                       
                    $('#'+id).removeClass('error');
                    $('#'+id).prev().removeClass('error')
                    $('#'+id).next().remove()
                    $('#'+id).parent().addClass('success');
                }
            }

        },
        error:function(){
        },
    });
});
