【问题描述】：

我想建立两列，第一列应包含FirstList 的项目，第二列应包含SecondList 的项目。为什么在我的实现中将一列放在另一列之下？如何解决这个问题？我需要使用 css 样式而不是 html？

控制器和类：

namespace MvcApplication4.Controllers

public class HomeController : Controller

    //
    // GET: /Home/

    public ActionResult Index()
    
        List<Employee> emp1 = new List<Employee>();
        emp1.Add(new Employee  Number="1",Text="dfsfdsfsafdsafdasfadsf");
        emp1.Add(new Employee  Number = "2", Text = "asdfsa" );
        emp1.Add(new Employee  Number = "3", Text = "dfsfdsfdasfsafdsafdasfdsafsaadsf" );
        List<Employee> emp2 = new List<Employee>();
        emp2.Add(new Employee  Number = "1", Text = "dfsfdsfsafdsafdasfadsf" );
        emp2.Add(new Employee  Number = "2", Text = "asdfsa" );
        emp2.Add(new Employee  Number = "3", Text = "dfsfdsfdasfsafdsafdasfdsafsaadsf" );
        emp2.Add(new Employee  Number = "4", Text = "asdfsa" );
        emp2.Add(new Employee  Number = "5", Text = "dfsfdsfdasfsafdsafdasfdsafsaadsf" );
        return View(new IndexViewModel  FirstList = emp1, SecondList = emp2 );
    

public class IndexViewModel

    public IEnumerable<Employee> FirstList  get; set; 

    public IEnumerable<Employee> SecondList  get; set; 

public class Employee

    public string Text  get; set; 

    public string Number  get; set; 

索引.cshtml

@model MvcApplication4.Controllers.IndexViewModel
@
    ViewBag.Title = "Index";


<h2>Index</h2>

<table>

<tbody>
    @foreach (var item in Model.FirstList)
    
        <tr>
            <td>@item.Number</td>
            <td>@item.Text</td>
        </tr>
    
    @foreach (var item in Model.SecondList)
    
        <tr>
            <td>@item.Number</td>
            <td>@item.Text</td>
        </tr>
    
</tbody>
</table>

【参考方案1】：

您将两个模型的值直接写到同一个表中。为了实现我认为您正在尝试做的事情，您需要将值分隔到单独的表中，并使用 HTML 和 CSS 相应地定位它们。

   @model MvcApplication4.Controllers.IndexViewModel
@
    ViewBag.Title = "Index";


<h2>Index</h2>

<table>

<tbody>
    @foreach (var item in Model.FirstList)
    
        <tr>
            <td>@item.Number</td>
            <td>@item.Text</td>
        </tr>
    
</tbody>
</table>
<table>
<tbody>
   @foreach (var item in Model.SecondList)
    
        <tr>
            <td>@item.Number</td>
            <td>@item.Text</td>
        </tr>
    
</tbody>
</table>

【参考方案2】：

此代码按您的预期工作：

<table border="1">
    <thead>
        <th colspan="2">First List</th>
        <th colspan="2">Second List</th>
    </thead>
    <tbody>
        @for (int i = 0; i < Math.Max(Model.FirstList.Count(), Model.SecondList.Count()); i++)
        
            Employee  first = Model.FirstList.Count() > i ? Model.FirstList.ToList()[i] : null;
            Employee second = Model.SecondList.Count() > i ? Model.SecondList.ToList()[i] : null;
            <tr>
                <td>@(first?.Number)</td>
                <td>@(first?.Text)</td>
                <td>@(second?.Number)</td>
                <td>@(second?.Text)</td>
            </tr>
        
    </tbody>
</table>

您应该合并两个 foreach 循环以并排显示列表。
