How to combine matrixes

Question

I'm a complete beginner so please bear with me!

I have data that looks like this:

Id	Test 1	Test 2	Test 3
1	ok	ok	ko
2	ok	ko	ko
3	ok	ok	ok
4	ko	ko	ko
5	ok	ko	ko

I would like a table that count every "ok" and "ko", test by test so ideally, I would get something like this:

	test 1	test 2	test 3
ok	4	3	1
ko	1	2	4

I could just do 3 simple matrix with "test 1" as a row and "count of test 1" as values but I'm sure there's an easy way to combine them as one table, I just can't figure it out.
