How to order cell rows

I have a large cell (174x4 cell). I've attached a smaller working example. This takes the form of x for Copy(:,1), y for Copy(:,2) , ID for Copy(:,3) and a weight for Copy(:,4). I would like to for each row, sort by ascending x order i.e. what is in Copy(i,1) for i=3 rows in my small example. I want to retain the pairings of y, ID and weight. So sort only by x. Is this possible for a cell like so?

Many thanks.

[per isakson]

Copy = 
    [ 2x1 double]    [ 2x1 double]    [ 2x1 double]    [ 2x1 double]
    [33x1 double]    [33x1 double]    [33x1 double]    [33x1 double]
    [20x1 double]    [20x1 double]    [20x1 double]    [20x1 double]

Try this function

function    sorted_copy = cssm( Copy )
    sorted_copy = cell( size( Copy ) );
    for rr = 1 : size(Copy,1)  %  for each row
        [~,ixs] = sort( Copy{rr,1}, 'ascend' );
        for cc = 1 : size(Copy,2) % retain the pairings 
            sorted_copy{rr,cc} = Copy{rr,cc}(ixs);
        end
    end
end
