How to add Hyperlink and button column in Datatable Grid

buntym

var tblN = $('#MyTable').DataTable({
    responsive: true,
    dom: 'Bfrtip',
    buttons: [
       'copy',
       'excel'
    ],
    data: itemsArr,
    columns: [
           { data: 'MainCol' },
           { data: 'Col1' },
           { data: 'Col2'},
           { data: 'total' }
    ],
});

the above data is coming from AJAX web service call and we have used the columns to set the data table with column name. Now I want to add one more extra column with Hyperlink and button column in Grid but I was not able to do so. I have tried columnDefs, columns.render, and other articles on Custom column and also refer following article:
https://datatables.net/release-datatables/examples/ajax/null_data_source.html

but not able to add them. Please help me with the data: myItemArray and suggest me the way to add column

One option is to use a renderer.
