How to apply a zip code mask to a datatable column using Javascript?

Question

I have a Datatable in my View Index that has the CEP column that needs to have a CEP mask (ex: 29780-000). Does anyone know how to do this using Javascript?

<table class="table table-hover table-bordered dataTable table-striped width-full center-header table-responsive" id="dtPrincipal">
            <thead>
                <tr>
                    <th>
                        @Html.DisplayNameFor(model => model.CepId)
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.Endereco)
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.Complemento)
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.Bairro)
                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.Cidade)
                    </th>

Answer 1

Use the settings columnDefs, inform which column you want to format by targets and in render receives a formatting function that can be applied, example:

"render": function(data, type, row) {
    return data.substring(0, 5) + "-" + data.substring(5);
}

Complete minimum example:

$(document).ready(function() {
  $('#example').DataTable({
    "columnDefs": [{
      "targets": [0],
      "visible": true,
      "searchable": false,
      "render": function(data, type, row) {
        return data.substring(0, 5) + "-" + data.substring(5);
      },
    }]
  });
});

Answer 2

Another alternative is to bring your ZIP code already formatted in the Model

Model:

    public string CEP { get; set; }
    public string CepFormatado { get {
            if(CEP != null)
                return Convert.ToUInt64(CEP).ToString(@"00000\-000");
            return string.Empty;
        }
    }

View:

<table class="table table-hover table-bordered dataTable table-striped width-full center-header table-responsive" id="dtPrincipal">

                <tr>
