You can use JQuery each to assign IDs to TR Element.It simply saves you the boilerplate code of incrementing the index and getting the value at that index.

    $('#edit-submitted-new-table-element tr').each(function(index){
       $(this).prop("id","id_"+index);
    });

You add id to tableTr. It is a collection of tr, not one of the trs. Thanks to @C-linkNepal. id attribute can not start with number, you must add some letter before it.

tableTr.eq(i).attr('id', 'id' + i);
