同一数据集中具有父子关系的 JQuery 数据表。如何将其显示为表中的父子行？

var g_dataFull = [];

/* Formatting function for row details - modify as you need */
function format ( d ) {
    var html = '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;" width="100%">';

            '<td>' +  $('<div>').text(this.position).html() + '</td>' + 
            '<td>' +  $('<div>').text(this.office).html() +'</td>' +
