How to print two Different Tables using jspdf-autotable

Question

I want to print these two tables as pdf using jspdf autotable plugin. But the script that I wrote prints only second table. I think the problem lies in writing script. Will someone guide me how to print these two tables using jspdf-autotable.

        <button onclick="generate()">Print</button>

<table id="tbl1" border="2">
            <thead>
                <tr>
                    <th>ID</th>
                    <th>Name</th>
                    <th>Address</th>
                    <th>Marks</th>
                </tr>
            </thead>
            <tbody>
                <tr>
                    <td>01</td>
                    <td>Johnson</td>
                    <td>UK</td>
                    <td>112</td>
                </tr>
                <tr>
                    <td>02</td>
                    <td>Jim</td>
                    <td>US</td>
                    <td>142</td>
                </tr>
                <tr>
                    <td>03</td>
                    <td>Johnson</td>
                    <td>UK</td>
                    <td>112</td>
                </tr>
                <tr>
                    <td>04</td>
                    <td>Jim</td>
                    <td>US</td>
                    <td>142</td>
                </tr>
            </tbody>
        </table>
        <table id="tbl2" border="2">
            <thead>
            <tr>
                <th>First Name</th>
                <th>Last Name</th>
                <th>Phone</th>
                <th>Remarks</th>
            </tr>
            </thead>
            <tbody>
            <tr>
                <td>Julia</td>
                <td>Anderson</td>
                <td>2312144</td>
                <td>Good</td>
            </tr>
            <tr>
                <td>Emma</td>
                <td>Watson</td>
                <td>24564456</td>
                <td>Excellent</td>
            </tr>
            <tr>
                <td>Jim</td>
                <td>Carry</td>
                <td>5645648</td>
                <td>Seperb</td>
            </tr>
            <tr>
                <td>Harry</td>
                <td>Potter</td>
                <td>544562310</td>
                <td>Ridiculous</td>
            </tr>
            </tbody>
        </table>

this is script:

<script>
    function generate() {
        var doc = new jsPDF('p', 'pt', 'A4');

        var res = doc.autoTableHtmlToJson(document.getElementById("tbl1"), true);
        doc.autoTable(res.columns, res.data, {margin: {top: 80}});

        var res2 = doc.autoTableHtmlToJson(document.getElementById("tbl2"), true);
        doc.autoTable(res2.columns, res2.data, {margin: {top: 80}});

        doc.save("test.pdf");

    }
</script>

The second table is most likely printed on top of the first one. You would have to specify the start position of the second table like so:

var res = doc.autoTableHtmlToJson(document.getElementById('tbl1'));
doc.autoTable(res.columns, res.data);
var res2 = doc.autoTableHtmlToJson(document.getElementById('tbl2'));
doc.autoTable(res2.columns, res2.data, {
    startY: doc.lastAutoTable.finalY + 50
});
