How can I combine bysort with tabulate and export all of the tables into Excel?

Question

I have a dataset that has rankings for cars (New, not new, medium, old) as a string variable. Another variable is also a string variable that functions as a dummy (car has 4 wheels is “yes”, while car doesn’t have 4 wheels is “no”). How do I find the share of cars that have four wheels, but for each of the rankings of cars? For the first table will give me the proportion of cars with 4 wheels out of all “new” cars, as well as the proportion of cars without 4 wheels out of all “new cars”. This repeats for each ranking of car.

I tried bysort Car_rankings: eststo tabulate four_wheels but it doesn’t work. What should I do?

Car_rankings	four_wheels	id
New	yes	AJ4123
not new	yes	AK124
medium	no	KL41241
old	yes	ANV41223

This is just an example dataset and my actual one has many more rows.
