Hi,
Modifying views require some PHP/Development skills.
The code you paste is first wrong and second, incomplete.
In PHP, the code is wrong and will generate a PHP fatal error. You have a mix between a simple column title and a sorted column title.
In HTML, the open "th" does not have is closing one.
A fixed version:
<th class="title"><?php echo JText::_('PRODUCT_PRICE'); ?></th>
But even if you move/add something in the head of the table, you have to add the content in the table body too.
Regards,
