How do I top align all cells in Excel when using the export option of datatables?

Is there a way to top align all the cells in excel when using export feature of datatables? I am able to wrap the text in excel as well as I have marked “stripNewlines” as false. It works, however the cells are bottom aligned, so it is very hard for the user to read. Is there a way to top align the cells? Thanks.

Here is my code:

customize: function( xlsx ) {
                var sheet = xlsx.xl.worksheets['sheet1.xml'];

               $('row c[r^="B"]', sheet).attr( 's', '55' );
                 $('row c[r^="C"]', sheet).attr( 's', '55' );
                 $('row c[r^="A"]', sheet).attr( 's', '55' );
                 $('row c[r^="D"]', sheet).attr( 's', '55' );
                 $('row c[r^="E"]', sheet).attr( 's', '55' );
                 $('row c[r^="F"]', sheet).attr( 's', '55' );            
            $('row:nth-child(2) c', sheet).attr('s', '2');
              $('row:nth-child(1) c', sheet).attr( 's', '2' );
         $('row c[r^="A1"]', sheet).attr( 's', '51' );    
            },
                exportOptions: {
                    columns: ':visible',
                    stripNewlines: false

                                    }
            },
