Sort 3D matrix depending on specific column

Hello,
I have 3D matrix (10*10*4) and I am trying to short each slice depending on the 2 column after that and depending on column 2 I want to delete all rows that have a value on column 2 less than 1 and greater than 17.
I used this code to sort but it is not working
clc;
clear;
A = rand(10,10,4)
column = 2;
[values,indices] = sort(A(:,column,:))
B = A(indices,:,:)
Thanks

After deleting some rows, your slices will get different sizes, have you thought about that?

%-----------Example----------
A=randi(30,10,10,4)
%--------------------------------
out=cell(1,k);
for k=1:size(A,3)
a=A(:,:,k);
b=sortrows(a,2);
c2=b(:,2);
b(c2<1 | c2>27,:)=[];
out{k}=b
end
