patrick I need to add a custom column inside the cart products for "Installation Charges" For each product, that will be different installation charges. I can switch that to cart using woocommerce _add_cart_item_data action hook.
James You can do it by overwriting the Woocommerce templates. Take a look at the woocommerce template structure https://docs.woocommerce.com/document/template-structure/. You need to modify the wp-content/woocommerce/templates/cart/cart.php template as per your requirements.
