Inside form assign employee reference to a input of type hidden and give a name to that attribute 在内部表单中，将员工引用分配给隐藏类型的输入，并为该属性命名
<input name="emp" value="<%=e%>" type="hidden">
Based on emp id retrieve data from db 基于emp id从数据库检索数据
In servlet read that parameter from request object reference 在servlet中，从请求对象引用中读取该参数
And for table border use border attribute in table opening tag 对于表格边框，请在表格开头标签中使用border属性
<table border="1">

Once you hit the "submit" button you are sending a request to the server. 点击“提交”按钮后，您将向服务器发送请求。
You can access the request parameters with request object as below 您可以使用以下请求对象访问请求参数
request.getParameter("parameter name");
in your case to access the Customer contact number first assign a name to it,then access it in servlet as mentioned above. 如果您要访问客户联系电话，请先为其分配一个名称，然后如上所述在servlet中对其进行访问。
