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?

Hello,
Thank you for your reply. No, it will the same. because this data is a grid and I checked that. but I will get new 3D matrix with new size

%-----------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
