I have a large table like this: (the first row is column name "E" and "M")
I want to know how many "blc" has "m" and how many "blc" has "f" and the same thin for "whi". Any idea how?

Use groupsummary. Group the data first by E then by M. Groupsummary will tell you the count of each group. Here's an example using the name data for the table.
summaryTbl = groupsummary(data,["E","M"])
summaryTbl =
4×3 table
E M GroupCount
_____ ___ __________
"blc" "f" 4
"blc" "m" 2
"whi" "f" 3
"whi" "m" 3

Cell vs string. Might have an older version of MATLAB.

Ah true, but groupsummary() was introduced in 2018a hence the OP has access to string classes which was there even before 2018 (2016b I believe).
