我需要值 3000 在 csv 文件中，请帮助

我的功能 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js">





        var $rows = $table.find('tr:has(td)'),

            // Temporary delimiter characters unlikely to be typed by keyboard
            // This is to avoid accidentally splitting the actual contents
            tmpColDelim = String.fromCharCode(11), // vertical tab character
            tmpRowDelim = String.fromCharCode(0), // null character

            // actual delimiter characters for CSV format
            colDelim = '","',
            rowDelim = '"\r\n"',

            // Grab text from table into CSV formatted string
            csv = '"' + $rows.map(function (i, row) {
                var $row = $(row),
                    $cols = $row.find('td');

                return $cols.map(function (j, col) {
                    var $col = $(col),
                        text = $col.text();

                    return text.replace(/"/g, '""'); // escape double quotes

                }


</script>

现在写我正在获取数据为“”，“”，“”，“，”，“”，“”的csv文件，
