如何在jquery jtable中获取字段的值

<table id="myTable"></table>

$('#myTable').jtable({
    title: 'Table Title',
    fields: {
        id: {
            title: 'ID',
            key: true,
            list: false
        },
        name: {
            title: 'Name'
        },
        age: {
            title: 'Age'
        }
    },
    actions: {
        listAction: '/getData' // 数据源的URL
    }
});

<?php
$data = array(
    array('id' => 1, 'name' => 'John', 'age' => 25),
    array('id' => 2, 'name' => 'Jane', 'age' => 30),
    array('id' => 3, 'name' => 'Bob', 'age' => 35)
);

header('Content-Type: application/json');
echo json_encode(array('Result' => 'OK', 'Records' => $data));
?>

$(document).ready(function() {
    $('#myTable').jtable('load');
});
