我的任务是制作一个轮班网络应用程序，该应用程序可以帮助我现有的员工跟踪工人的轮班情况。他们给了我一个网站StaffHub，我应该根据它为我的Web应用程序建模，目前正在日历部分工作。
日历具有三个视图： 1.每月 2.每周一次 3.每天
根据我目前的水平技能，我每周都在工作。 每周完成一次后，我将依次进入“每月”和“每日”
日历的算法：
将年份分为几周，基本上每周从特定日期的星期一开始。今天是1/14/2019，所以直到2019年1月20日为止是有几天的。用户列表组成的这个天数范围是表格，表格的每一行中有7天，其中有一个选择选项，其中包含三个选项“第一班”，“第二班”，“第三班”和“关闭” “ （selectTag仅用于演示目的）。为此，制作了一个html表，该表执行以php和Symfony 2.7编写的POST，将select选项的选择发送到后端并保存在后端。然后GET从后端获取数据。
这是树枝文件的前端：

如何更新HTML数据表。 从GET API返回的日期看起来像这样：
[
{
"period": "2019-01-07 00:00:00",
"username": "gbinaku",
"shift": "audi"
},
{
"period": "2019-01-13 00:00:00",
"username": "gbinaku",
"shift": "audi"
},
{
"period": "2019-01-07 00:00:00",
"username": "abc123",
"shift": "audi"
},
{
"period": "2019-01-09 00:00:00",
"username": "ekransiqi",
"shift": "saab"
},
{
"period": "2019-01-11 00:00:00",
"username": "gbinaku",
"shift": "mercedes"
},
{
"period": "2019-01-11 00:00:00",
"username": "abc123",
"shift": "mercedes"
},
{
"period": "2019-01-09 00:00:00",
"username": "burim",
"shift": "audi"
},
{
"period": "2019-01-07 00:00:00",
"username": "albertina",
"shift": "saab"
},
{
"period": "2019-01-08 00:00:00",
"username": "kini",
"shift": "audi"
},
{
"period": "2019-01-10 00:00:00",
"username": "burim",
"shift": "mercedes"
},
{
"period": "2019-01-08 00:00:00",
"username": "cvb1",
"shift": "saab"
},
{
"period": "2019-01-07 00:00:00",
"username": "ragnar",
"shift": "mercedes"
},
{
"period": "2019-01-11 00:00:00",
"username": "cvb1",
"shift": "saab"
},
{
"period": "2019-01-12 00:00:00",
"username": "ragnar",
"shift": "audi"
},
{
"period": "2019-01-13 00:00:00",
"username": "teab",
"shift": "mercedes"
},
{
"period": "2019-01-07 00:00:00",
"username": "cvb1",
"shift": "audi"
}
]
但是这里有句号，用户名和Shift，如何从JSON响应信息中相应地更新HTML表。
