Hi Laughen,
Thank you for your purchase.

You can try with this one. You have to replace #table_1 selector with your actual table selector.

jQuery(window).load(function() {
    var clickRow = jQuery("#table_1").on('click', 'tbody tr', function() {
        var id = jQuery(this).find("td:first").text();
        alert(id);
    }).DataTable();
});

Hi Lughen,

No you can select any column. You can call var id how do you want and td:first is first column. You can change it to select any other column.
