Formatting JSON output into a tabular grid

$.ajax({
                  type: 'post',
                  url: something.do,
                  data: $('#someForm').serialize(),
                  success: function(jsonResponse) {
                        if(jsonResponse.errorMap != null) {
                              alert(jsonResponse.errorMap);
                        } else if (jsonResponse.transactionPage != null) {
                              showData(jsonResponse.transactionPage); // instead of this I want it to loop and iterate and paint data as given below...
                        }
                  }
            });  





This showData method gets me unformatted data. I want to format it in a tabular grid in a modal window (JSP).

This is the data that is getting returned

{
  "transactions":
  [
    {
      "error": "",
      "ctrNum1": "123456789",
      "successful": true
    },
   
    {
      "error": "",
      "ctrNum2": "123456791",
      "successful": true
    },
    {
      "error": "",
      "ctrNum3": "123456792",
      "successful": true
    },
    {
      "error": "",
      "ctrNum4": "123456793",
      "successful": true
    }
  ]
}


Also I need iterate or loop in dynamically.



I want to paint the data in a tabular format upon success.

success: function(jsonResponse) {
               if(jsonResponse.errorMap != null){
                alert(jsonResponse.errorMap);
               }else if(jsonResponse.transactionSummary != null){
                  var trans = jsonResponse.transactionSummary;
                  var date =  json.transactionDate;
                      var html = "";
                        alert(jsonResponse.transactionSummary);
                        alert(jsonResponse.transactionSummary.ctrNum);
                        for (var i=0; i < trans.length; i++) {
                              html += "<div><div>" +  (i + 1) + "</div><div>" + trans.ctrNum + "</div>";
                             
                              if (trans.successful == true) {
                                    html += "<div>Successful</div></div>"
                              } else {
                                    html += "<div>" + trans.error + "</div></div>"
                              }
                        }
                 
                  //showData(jsonResponse.transactionSummary);
                  }
              }
