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!
Here’s the result: cart is sorted alphabetically, and each cart section is now delimited by the first cart item title letter.
