Answer 1

Ok Found solution just add string_limit in addcolumn or addColumnAfter function in grid.php

$this->addColumnAfter('addons', array(
            'header' => Mage::helper('sales')->__('Addons'),
            'filter'    => false,
            'sortable'  => false,            
            'index' => 'addons',
            'type'  => 'text',
            'string_limit'  => '500', /* added for content limit */

        ), 'billing_name');
