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: "xx@hotmail.com"},
{ name : "Jack", age:50, email: "xxx@hotmail.com"},
{ name : "Son", age:45, email: "xxxx@hotmail.com"}
........................etc
];
这就是它的样子。我想知道如何将它显示为一个动态表。
你是这样做的:

var rows = [{
name: "John",
age: 20,
email: "xx@hotmail.com"
}, {
name: "Jack",
age: 50,
email: "xxx@hotmail.com"
}, {
name: "Son",
age: 45,
email: "xxxx@hotmail.com"
}];
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;

html+="</table>";
$("div").html(html);
});

const Array2Table = (arr) => {

let cells = [];
for (let property in arr[i]) {

top_row.push(`<th scope="col">${property}</th>`);
}

cells.push(`<td>${null}</td>`);
} else {

}
}

}
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() {
let html = Array2Table(rows);
$("div").html(html);
});
