Because “split” might not be the correct term, let me explain this better.
Let’s imagine your WooCommerce cart table is sorted by A>Z (with my WooCommerce cart sorting snippet for example). If your business model and/or UX requires it, then you might need to “add a cart table row” to communicate the fact those items belong to that letter:
- A
- Item 1 Title: “AAA”
- Item 2 Title: “ACC”
- B
- Item 3 Title: “BDD”
- Item 4 Title: “BEE”
Once again, this might sound incomprehensible so you’d better look at the screenshot below. Enjoy!

PHP Snippet: Split Cart by A>Z (Display Letter Above Each Section)
Note: you also need to use https://businessbloomer.com/woocommerce-sort-cart-items-alphabetically-az/ in order to sort your cart alphabetically first.
