Exclude column from export in jQuery Datatables

Question

I'm using jQuery datatable 1.10.11 and it's export button functionality as described here:

I want to skip last column from being export into excel file as this column has edit/delete buttons in it. My columns are generated dynamically so I can't use following method:

    $('#reservation').DataTable({
    dom: 'Bfrtip',
    buttons: [
        {
            extend: 'excel',
            text: 'Export Search Results',
            className: 'btn btn-default',
            exportOptions: {
                columns: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
            }
        }
    ]
});

I know this question is asked multiple time but non of them worked for me, might be version issue.

Answer 1

Try using CSS selector that excludes last column for columns option.

$('#reservation').DataTable({
   dom: 'Bfrtip',
   buttons: [
      {
         extend: 'excel',
         text: 'Export Search Results',
         className: 'btn btn-default',
         exportOptions: {
            columns: 'th:not(:last-child)'
         }
      }
   ]
});

Answer 2

You can add a class:

<th class='notexport'>yourColumn</th>

then exclude by class:

$('#reservation').DataTable({
   dom: 'Bfrtip',
   buttons: [
   {
        extend: 'excel',
        text: 'Export Search Results',
        className: 'btn btn-default',
        exportOptions: {
            columns: ':not(.notexport)'
        }
    }]
});

Answer 3

I just thought I'd add this in because the accepted answer only works to exclude if you are not already including something else (such as visible columns).

In order to include only visible columns except for the last column, so that you can use this in conjunction with the Column Visibility Button, use

$('#reservation').DataTable({
    dom: 'Bfrtip',
    buttons: [
    {
        extend: 'excel',
        text: 'Export Search Results',
        className: 'btn btn-default',
        exportOptions: {
            columns: ':visible:not(:last-child)'
        }
    }]
});

And if you want to explicitly add your own class:

    $('#reservation').DataTable({
    dom: 'Bfrtip',
    buttons: [
    {
        extend: 'excel',
        text: 'Export Search Results',
        className: 'btn btn-default',
        exportOptions: {
            columns: ':visible:not(.notexport)'
        }
    }]
});

for Excel, csv, and pdf

dom: 'lBfrtip',
buttons: [
    {
        extend: 'excelHtml5',
        text: '<i class="fa fa-file-excel-o"></i> Excel',
        titleAttr: 'Export to Excel',
        title: 'Insurance Companies',
        exportOptions: {
            columns: ':not(:last-child)',

        }
    },
    {
        extend: 'pdfHtml5',
        text: '<i class="fa fa-file-pdf-o"></i> PDF',
        titleAttr: 'PDF',
        title: 'Insurance Companies',
