Hello Guys,

    In this tutorial we will see how to add datatable custom export button example. datatable provide inbuilt button functionality and also provide html5 buttons so, as per your requirement you can add datatable export button in your table.

    Datatable also provide many customization functionality. so, in this example we will see how to add datatable export button outside table. many times we required this types of requirements so today I will give you example of datatable export button outside table.

    So, let's start to implement datatable custom export button example.

    In your html file add div with id or class out of table like below code :

<div id="buttons"></div>
<table id="example" class="table">
...
</table>

    using this function you can add buttons in any where outside of the datatable.

    In this step first initialize datatable 

var table = $('#example').DataTable();

    after that using datatable button function we can add button outside table like below code

var buttons = new $.fn.dataTable.Buttons(table, {
     buttons: [
       'copyHtml5',
       'excelHtml5',
       'csvHtml5',
       'pdfHtml5'
    ]
}).container().appendTo($('#buttons'));

    Example : 

     Directly apply buttons to datatable like below code :

    So, both way to you can implement custom export button outside datatable.

var table = $('#example').DataTable({
    buttons: [
       'copyHtml5',
       'excelHtml5',
       'csvHtml5',
       'pdfHtml5'
    ]
});

table.buttons().container().appendTo($('#buttons'))
