在动态表中显示对象数组javascript[重复]

Question

我想使用JavaScript在动态表中显示一个对象数组。

var rows=[{ name : "John", age:20, email: "[e-mail]"},
    { name : "Jack", age:50, email: "[e-mail]"},
    { name : "Son", age:45, email: "[e-mail]"}
........................etc
   ];

这就是它的样子。我想知道如何将它显示为一个动态表。

var rows = [{
    name: "John",
    age: 20,
    email: "[e-mail]"
}, {
    name: "Jack",
    age: 50,
    email: "[e-mail]"
}, {
    name: "Son",
    age: 45,
    email: "[e-mail]"
}];

var html = "<table border='1|1'>";
for (var i = 0; i < rows.length; i++) {
    html+="<tr>";
    html+="<td>"+rows[i].name+"</td>";
    html+="<td>"+rows[i].age+"</td>";
    html+="<td>"+rows[i].email+"</td>";
    
    html+="</tr>";

}
html+="</table>";
document.getElementById("box").innerHTML = html;

  for (let i = 0; i < arr.length; i++) {
    let cells = [];

    for (let property in arr[i]) {
      if (top_row.length < Object.keys(arr[i]).length) {
        top_row.push(`<th scope="col">${property}</th>`);
      }
      if (arr[i][property] === null) {
        cells.push(`<td>${null}</td>`);

  Table.push(`<table class="table card-table table-striped">`);
  Table.push(`<thead>${top_row.join("")}</thead>`);
  Table.push(`<tbody>${rows.join("")}<tbody>`);
  Table.push("</table>");
  return Table.join("");

$(function() {

  $("div").html(html);
