None of the Mathworks supplied tools for writing out matrices support that, so you will need to construct it yourself.

col_widths = [3 12 etc];
fmt_cell = [sprintfc('%%%ds', col_widths), '\n'];
fmt = [fmt_cell{:}];
your_cell_transpose = your_cell.';
fid = fopen('YourFile.txt', 'wt');
fprintf(fid, fmt, your_cell_transpose{:});
fclose(fid);
