如何将obj对象变成绘制成图片的样子

 const obj = {

Object.keys(obj)得到序号依次遍历，然后再依次遍历data生成行

<style>
    table.good {
        border-collapse: collapse
    }

        table.good td {
            border: solid 2px #000;
            padding: 3px 5px;
            text-align: center
        }

        table.good tr td:first-of-type {
            text-align: left
        }
</style>
<div id="dvHtml"></div>
