    $tablerow.each(function(index, value){
        $("table.table-editor tr:eq("+index+") td:eq(-1)").remove();
    });
});

$('#addrow').click(function() {
    
    var $input = $('<input>', {
        type: 'text',
        maxlength: '2',

    $('table.table-editor').append("<tr></tr>");
    $('table.table-editor tr:eq(0) td').each(function(index, value){
        $("table.table-editor tr:eq(-1)").append($input.append($input));
        $("input:text").attr("size", "2");
    });
});

$('#remrow').click(function() {
    $('table.table-editor tr:eq(-1)').remove();
});

1. Некорректно работает добавление строк. Как это исправить?
2. Хочу, чтоб при добавлении новых ячеек в placeholder писалось а(номер столбца),(номер строки)
