访问嵌套的json对象

I am trying to access JSON objects in JavaScript and display them in HTML table, I managed to do it but failed to display one of the columns.

project link

<script>
        var arrItems = [];      // THE ARRAY TO STORE JSON ITEMS.
        $.each(data.glance, function (index, value) {
            arrItems.push(value);       // PUSH THE VALUES INSIDE THE ARRAY.


        // EXTRACT VALUE FOR TABLE HEADER.
        var col = [];
        for (var i = 0; i < arrItems.length; i++) {
            for (var key in arrItems[i]) {
                if (col.indexOf(key) === -1) {
                    col.push(key);
                }
            }
        }

        // CREATE DYNAMIC TABLE.
        var table = document.createElement("table");

        // CREATE HTML TABLE HEADER ROW USING THE EXTRACTED HEADERS ABOVE.

        var tr = table.insertRow(-1);                   // TABLE ROW.

        for (var i = 0; i < col.length; i++) {
            var th = document.createElement("th");      // TABLE HEADER.
            th.innerHTML = col[i];
            tr.appendChild(th);
        }

        // ADD JSON DATA TO THE TABLE AS ROWS.
        for (var i = 0; i < arrItems.length; i++) {

            tr = table.insertRow(-1);
            data
            for (var j = 0; j < col.length; j++) {
                var tabCell = tr.insertCell(-1);
                tabCell.innerHTML = arrItems[0];
                tabCell.innerHTML = arrItems[i][col[j]];
            }
        }

        // FINALLY ADD THE NEWLY CREATED TABLE WITH JSON DATA TO A CONTAINER.
        var divContainer = document.getElementById("daytoday");
        divContainer.innerHTML = "";
        divContainer.appendChild(table);
    });

Also, am trying to access images and display them in slider but not sure how to access the nested image object,

Question: Can someone show me how can I access the images?

Image slider page

 <script>

$('img[class="logo"]').attr('src',data.logo);
$('div[class="header_bg"]').css('background-image', 'url(' + data.topbanner + ')');
//alert(JSON.stringify(data.property_images));
var countDown=0;
$.each(data.property_information,function(key,value){
  if(key!='NGORONGORO SOPA LODGE'){
  //alert(key);
    var cont="";
    var innerDivTop ='<div class="centre-container">'
                        +'<div  class="page-content">'
                        +'<div class="flex">'
                         +'<div class="body" style="width: 100%;">'
                          +'<div class="content-block"><h2 style="font-weight:bold">'+key+'</h2>'
                           +'<div class="flexslider">'
                              +'<div class="arrow-next" data-role="'+countDown+'"></div>'
                               +'<div class="arrow-back" data-role="'+countDown+'"></div>'
                                +'<ul class="services dynmic_'+countDown+'" >';



    for(var i=0;i<value.length;i++) {

      if(i==0) {
       // alert(value[i]);
       // console.log(value[i]);

       cont +='<li style="display: block;"><img src="'+value[i]+'" alt="" style="width:1088px;height:430px;" ></li>';

      } else {
        cont +='<li><img src="'+value[i]+'" alt="" style="width:1088px;height:430px;"></li>';

      } 
    }

        var innerDivBot='</ul>'
                          +'</div></div></div></div></div></div>';
 $('#contentRpt').append(innerDivTop+cont+innerDivBot);
 countDown +=1;
 }
});

Here is my Json data example :

"Day 1": {
  "location": "ARUSHA",
  "property": "THE ARUSHA HOTEL"

    You are trying to show a property name so you a nested loop here first to access object property and its value and then a second loop to extract values from value you extract in outer loop.

    Try like this

    $(function() {
      table = $("<table></table>").appendTo("#daytoday");
      table.append("<tr><th>DAY</th><th> LOCATION </th><th> HOTEL </th></tr>")
      $.each(data.glance, function(index, value) {
        row = $("<tr></tr>").appendTo(table);
        $("<td></td>").appendTo(row).html(index);
    
        $.each(value, function(i, v) {
          $("<td></td>").appendTo(row).html(v);
        });
      });
    
    });
    

    var data = {
      "glance": {
        "Day 1": {
          "location": "ARUSHA",
          "property": "THE ARUSHA HOTEL"
        },
        "Day 2": {
          "location": "TARANGIRE NATIONAL PARK",
          "property": "TARANGIRE SAFARI LODGE"
        },
        "Day 3": {
          "location": "LAKE MANYARA NATIONAL PARK",
          "property": "LAKE MANYARA HOTEL"
        },
        "Day 4": {
          "location": "SERENGETI NATIONAL PARK",
          "property": "SERENGETI SOPA LODGE"
        },
        "Day 5": {
          "location": "SERENGETI NATIONAL PARK",
          "property": "SERENGETI SOPA LODGE"
        },
        "Day 6": {
          "location": "SERENGETI NATIONAL PARK",
          "property": "SERENGETI SOPA LODGE"
        },
        "Day 7": {
          "location": "NGORONGORO CONSERVATION AREA AUTHORITY",

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <div id="daytoday">
    
    </div>

    SECOND QUESTION :

    For your second question you need to loop through the image property of valve so you need to call your loop on value.images

    So change your inner for loop like this

    for (var i = 0; i < value.images.length; i++) {
    
        if (i == 0) {
            // alert(value[i]);
            // console.log(value[i]);
            cont += '<li style="display: block;"><img src="' + value.images[i] + '" alt="" style="width:1088px;height:430px;" ></li>';
    
        } else {
            cont += '<li><img src="' + value.images[i] + '" alt="" style="width:1088px;height:430px;"></li>';
    
        }
    }
    
    </div>
