jQuery split a table into two tables at a particular row number

Question

I need to split a table into two tables at a particular row number using jQuery. Can this be done?

I googled but couldn't find anything. jQuery's pretty powerful, I would have thought this can be done.

The table is not numbered so jQuery would need to index the rows.

Any help with this is very much appreciated.

jQuery Slice method will be useful in such case: documentation here

Add a table with some rows in html:

<table id="mainTable">
<tr>
    <td>Row 1</td>
    <td>Dummy Data</td>
</tr>
<tr>
    <td>Row 2</td>
    <td>Dummy Data</td>
</tr>
<tr>
    <td>Row 3</td>
    <td>Dummy Data</td>
</tr>
<tr>
    <td>Row 4</td>
    <td>Dummy Data</td>
</tr>
<tr>
    <td>Row 5</td>
    <td>Dummy Data</td>
</tr>
<tr>
    <td>Row 6</td>
    <td>Dummy Data</td>
</tr>
<tr>
    <td>Row 7</td>
    <td>Dummy Data</td>
</tr>
<tr>
    <td>Row 8</td>
    <td>Dummy Data</td>
</tr>
<tr>
    <td>Row 9</td>
    <td>Dummy Data</td>
</tr>
<tr>
    <td>Row 10</td>
    <td>Dummy Data</td>
</tr>
</table>

Slice n rows using jQuery, create new table instance and append rows:

<script type="text/javascript">
jQuery(document).ready(function() {
    var $mainTable = $("#mainTable");
    var splitBy = 5;
    var rows = $mainTable.find ( "tr" ).slice( splitBy );
    var $secondTable = $("#mainTable").parent().append("<table id='secondTable'><tbody></tbody></table>");
    $secondTable.find("tbody").append(rows);
    $mainTable.find ( "tr" ).slice( splitBy ).remove();
});
</script>
