Answer 1

您可以使用forEachmethod来做到这一点，它接受一个callback提供的函数作为参数。

var users=[{"firstName":"John", "last Name":"Doe", "age":"46"},
 {"firstName":"James", "last Name":"Blanc", "age":"24"}]
users.forEach(function(item){
  $('tbody').append('<tr><td>'+item.firstName+'</td><td>'+item["last Name"]+'</td><td>'+item.age+'</td></tr>')
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<thead>
<tr>
<th>firstName</th>
<th>last Name</th>
<th>age</th>
</tr>
</thead>
<tbody>

</tbody>
</table>

Answer 2

试试这个代码：

var rows = [{"firstName":"John", "last Name":"Doe", "age":"46"},
 {"firstName":"James", "last Name":"Blanc", "age":"24"}];
 var html = '<table>';
 html += '<tr>';
 for( var j in rows[0] ) {
  html += '<th>' + j + '</th>';
 }
 html += '</tr>';
 for( var i = 0; i < rows.length; i++) {
  html += '<tr>';
  for( var j in rows[i] ) {
    html += '<td>' + rows[i][j] + '</td>';
  }
  html += '</tr>';
 }
 html += '</table>';
 document.getElementById('container').innerHTML = html;

<div id="container">
</div>
