The example in this article describes the method of dynamically creating complex tables with jQuery+json. Share it with everyone for your reference, the details are as follows:

function SetSubTable() {
  var obj = jQuery.parseJSON($("#SubJsonStrValue").val());
  window.ALLPARAMTERS = obj;
  var row_str = "";
  var span_num = 1
  for (var i = 0; i < obj.length; i++) {
    if (obj[i].ParamNames.length > 0) {
      row_str += &#39;<tr><td rowspan="&#39; + obj[i].ParamNames.length + &#39;"><input type="checkbox" name="_&#39;+obj[i].Id+&#39;" />&#39; + obj[i].Name + &#39;</td>&#39;;
      for (var j = 0; j < obj[i].ParamNames.length; j++) {
        if (j != 0) {
          row_str += "<tr>";
        }
        row_str += &#39;<td><input type="checkbox" name="p_&#39;+obj[i].ParamNames[j].Id+&#39;_&#39;+obj[i].Id+&#39;" />&#39; + obj[i].ParamNames[j].Name + &#39;</td><td>&#39;;
        for (var k = 0; k < obj[i].ParamNames[j].ListItems.length; k++) {
          row_str += obj[i].ParamNames[j].ListItems[k].Name+"|";
        }
        row_str = row_str.substring(0, row_str.length - 2);
        row_str += "</td><td>";
        if (obj[i].ParamNames[j].CanMultiSelecte) {
          row_str += "多选";
        } else {
          row_str += "单选";
        }
        row_str += "</td></tr>";
      }
    }
  }
  $("#sub_table_header").after(row_str);
}
