Extract element from a table

I have a 56x4 table in which first column collects strings, while the other columns have non-null number.

edgetable=table(edgetype,edgeindex,firstnode,secondnode);

I would like to extract edgeindexes such that edgetype is equal, e.g., to "CSE".

Let's make a sample table.

rng default
listOfTypes = ["apple"; "banana"; "cherry"];
T = listOfTypes(randi(numel(listOfTypes), 5, 1));
x = randi(10, 5, 1);
tt = table(T, x)

tt = 5×2 table
       T        x 
    ________    __

    "cherry"     1
    "cherry"     3
    "apple"      6
    "cherry"    10
    "banana"    10

theCherries = tt(tt.T == "cherry", :)

theCherries = 3×2 table
       T        x 
    ________    __

    "cherry"     1
    "cherry"     3
    "cherry"    10
