为什么html helper开始格式化显示的方式

为什么在顶部添加BeginForm标签显示Edit and Details部分旁边的“Delete”按钮？附上代码和图片。为什么html helper开始格式化显示的方式

@foreach (var item in Model) 
{ 
    using (Html.BeginForm("Delete", "Employee", new { id = item.EmployeeID})) 
    { 
     <tr> 
      <td> 
       @Html.DisplayFor(modelItem => item.Name) 
      </td> 
      <td> 
       @Html.DisplayFor(modelItem => item.Gender) 
      </td> 
      <td> 
       @Html.DisplayFor(modelItem => item.City) 
      </td> 
      <td> 
       @Html.DisplayFor(modelItem => item.DepartmentID) 
      </td> 
      <td> 
       @Html.DisplayFor(modelItem => item.DateOfBirth) 
      </td> 
      <td> 
       @Html.ActionLink("Edit", "Edit", new { id = item.EmployeeID }) | 
       @Html.ActionLink("Details", "Details", new { id = item.EmployeeID }) | 
       <input type="submit" value="Delete" 
         onclick="return confirm('Are you sure you want to delete user @item.Name');" /> 

      </td> 
     </tr> 
    } 
}
