I have a drupal 7 view, consists of table. I need to add sort symbol (both asc and desc) in view header by default if no sorting applied.
I tried with altering views-view-table.tpl.php file, and added asc, desc images for each header.
But I need proper solution, Is there any hook there to alter the table headers?
