How to delete columns from 3D-array

Hello, i would like your help if possible. I have a 3D array. Lets say for example it is 2x5x2. The array is full. During the simulation it comes a time that the array has zeros in some columns. For example it has zeros in the 1st dimension for columns 2 and 4. How do i delete the zeros and then how can i shift the after value to take the zeros place and final replace the empty values by zeros.

Example:

Q(:,:,1) = 1 1 1 1 1; 2 2 2 2 2;

Q(:,:,2) = 3 3 3 3 3; 4 4 4 4 4;

During Simulation:

Q(:,:,1) = 1 0 1 0 1; 2 0 2 0 2;

Q(:,:,2) = 3 3 3 3 3; 4 4 4 4 4;

I want this to happen:

Q(:,:,1) = 1 1 1 0 0; 2 2 2 0 0;

Q(:,:,2) = 3 3 3 3 3; 4 4 4 4 4;

Thank you in advance

If the order of the nonzero elements isn't of significance or they're matching as the example then

>> Q(:,:,1) = [1 0 1 0 1; 2 0 2 0 2];
Q(:,:,2) = [3 3 3 3 3; 4 4 4 4 4];
>> Q(:,:,1)=sort(Q(:,:,1),2,'descend');
>> Q
Q(:,:,1) =
   1     1     1     0     0
   2     2     2     0     0
Q(:,:,2) =
   3     3     3     3     3
   4     4     4     4     4
