Como puedo calcular la edad automaticamente

Danirom

Hello, how are you, could someone help me to solve this problem please. I want to calculate the age from the fechanac column (date of birth). The age column is not a data that I get from the query that I make through ajax. Thank you very much.

tabla = $('#table_id').DataTable({

    /*"destroy": true,*/
    "processing": true,
    "serverSide": true,
    "ajax": {
        "url": "/Pacientes/GetPacientes",
        "type": "POST",
        "datatype": "json"
    },
    "bInfo": false,
    "pageLength": 10,
    "filter": true,
    "responsive": true,
    "responsivePriority": 1,
    "data": null,
    "columns": [
        { "data": "codigo", "name": "codigo", "autoWidth": true, "visible": false },
        { "data": "dni", "name": "dni", "autoWidth": true },
        { "data": "paciente", "name": "paciente", "autoWidth": true },
        { "data": "histclinica", "name": "hisclinica", "autoWidth": true },
        { "data": "fechanac", "name": "fechanac", "autoWidth": true },
        { "name": "edad"   },


        { "data": "sexo", "name": "sexo", "autoWidth": true },
        { "data": "peso", "name": "peso", "autoWidth": true },
        { "data": "talla", "name": "talla", "autoWidth": true },
        { "data": "direccion", "name": "direccion", "autoWidth": true },
        { "data": "localidad", "name": "localidad", "autoWidth": true },
        { "data": "provincia", "name": "provincia", "autoWidth": true },
        { "data": "profesion", "name": "profesion", "autoWidth": true },
        { "data": "celular", "name": "celular", "autoWidth": true },
        { "data": "mail", "name": "mail", "autoWidth": true },
        { "data": "responsable", "name": "responsable", "autoWidth": true },
        { "data": "fallecio", "name": "fallecio", "autoWidth": true },
        { "defaultContent": "<button type='button' value='Seleccionar' title='Actualizar Datos del Paciente' class='btn btn-secondary btn-modificar'><i class='bi bi-file-earmark-text' aria-hidden='true'></i></button>" },
        { "defaultContent": "<button type='button' value='Seleccionar' title='Eliminar Paciente' class='btn btn-default btn-eliminarpaciente'><i class='bi bi-trash' aria-hidden='true'></i></button>" },
        { "defaultContent": "<button type='button' value='Seleccionar' title='Obra Sociales del Paciente' class='btn btn-default btn-mutual'><i class='bi bi-file-earmark-plus' aria-hidden='true'></i></button>" }
    ],

Use columns.render to calculate the age from the fallecia column. Similar to this example except instead of concatenating two strings you would perform your age calculation.
