I got this div-table populated dynamically, but I can't find a way to add a header to it, given the way this is being built.

HTML piece:

<div class="block div-table" id="sidebar-record-block"></div>

This is the script populating the table dynamically:

function showRecord(record) {
    if (record.length) {
      for (var i = 0; i < record.length; i++) {
        // build field name on the fly, formatted field-1234
        var str = '' + i;
        var fieldId = 'field-' + ('0000' + str).substring(str.length)

        // If this field # doesn't already exist on the page, create it
        if (!$('#'+fieldId).length) {
          var newField = $($.parseHTML('<div id="'+fieldId+'"></div>'));
          $('#sidebar-record-block').append(newField);
        }

        // Replace content of the field div with new record
        $('#'+fieldId).replaceWith('<div id="'+fieldId+'" class="div-table-row"></div>');
        $('#'+fieldId).append('<input id=checkBox type="checkbox"</input>')
                      .append($('<div class="div-table-th">' + record[i].heading + '</div>'))
                      .append('<div class="div-table-td">' + record[i].cellval + '</div>')             
      }  
    }

Here's how css is:

.div-table {
    display: table;
    width: auto;
    border-spacing: 3px;
  }

  .div-table-row {
    display: table-row;
    width: auto;
    clear: both; 
 }

  .div-table-td,
  .div-table-th {
    display: table-cell;
    width: 190px;
    background-color: rgb(245, 241, 239);
  }

Here's the expected result: Appreciate your help!
