MATLAB: Deleting zeros from cell matrix without resizing or reshaping matrix

Question

I have a cell matrix like this

    [1]    [2]    [6]    [2]    [6]    [6]    [1]    [0]    [0]
    [1]    [7]    [2]    [5]    [0]    [6]    [4]    [7]    [1]
    [3]    [2]    [0]    [2]    [6]    [7]    [4]    [7]    [3]

and i want to delete zeros without changing the size or shape of the cell matrix

this the result i want

    [1]    [2]    [6]    [2]    [6]    [6]    [1]    []     []
    [1]    [7]    [2]    [5]    []     [6]    [4]    [7]    [1]
