从json (JSON.stringify(res[0]) )创建表-以字符串形式输出-应转换为html格式的表

var data = JSON.parse(JSON.stringify(res[0]));

var table = document.createElement("table");

// 创建表头
var thead = document.createElement("thead");
var headerRow = document.createElement("tr");
for (var key in data) {
  var th = document.createElement("th");
  th.textContent = key;
  headerRow.appendChild(th);
}
thead.appendChild(headerRow);
table.appendChild(thead);

// 创建表格内容
var tbody = document.createElement("tbody");
var contentRow = document.createElement("tr");
for (var key in data) {
  var td = document.createElement("td");
  td.textContent = data[key];
  contentRow.appendChild(td);
}
tbody.appendChild(contentRow);
table.appendChild(tbody);

var tableString = table.outerHTML;

document.getElementById("tableContainer").innerHTML = tableString;
