I add json data in database like this (in database column social):

{"twitter":"test","instagram":"test1","linkedin":"test2"}

for show result in datatables:

var tableUser = $('#table-user').DataTable({
    dom: 'rt<"card-footer"<"row" <"col-md-6"i> <"col-md-6"p>>>',
    processing: true,
    serverSide: true,
    autoWidth: false,
    order: [
        [1, 'asc']
    ],

    ajax: {
        url: '<?= route_to('admin/user/manage') ?>',
        method: 'GET'
    },
    columnDefs: [{
        orderable: false,
        targets: [0, 4, 5]
    }],
    columns: [
        {
            'data': function(data) {
                return data.social 
            },
        }
    ]
});

Result is(return data.social):

{"twitter":"test","instagram":"test1","linkedin":"test2"}

In action I need to specific value like: twitter or instagram. How to show this result?!
