Export HTML table with user input to CSV via javascript

Question

I am looking for a way to export my html table to a CSV file. I have already found a solution, unfortunately it seems to work only with static content. Does anyone know a way to export the table filled with user input?

I post the code below. I also made a fiddle https://jsfiddle.net/xn0agk7L/2/

<form action="#">
        <input type="button" value="Empfänger hinzufügen" onclick="addRow('myTable')"/>
        <input type="button" value="Empfänger löschen" onclick="deleteRow('myTable')"/>
        <div class="table-wrapper">
            <div class="table-scroll">
                <table id="myTable" border=1>
                    <tr>
                        <th>#</th>
                        <th>Geschlecht</th>
                        <th>Anrede</th>
                        <th>Vorname</th>
                        <th>Nachname</th>
                        <th>Titel</th>
                        <th>E-Mail</th>
                    </tr>
                    <tr>
                        <td>
                            <p>
                                <label>
                                    <input type="checkbox" name="chk"/>
                                    <span></span>
                                </label>
                            </p>
                        </td>

Try using Data Tables Jquery library. They have given very good documentation of everything related to it. You can export your html table to CSV, PDF, etc. and many more formats.
