如何在foreach期间将自定义列添加到表中

Question

您好我需要构建动态表,其中包含来自数组的列(标题)和来自其他数组的行,数组中的第一列必须是静态的.

<table>
<thead>
<tr>
<th>Static</th>
<th>Dynamic 1</th>
<th>Dynamic 2</th>
<th>Dynamic 3</th>
</tr>
</thead>
<tbody>
<tr>
<th>Nam1</th>
<th>value</th>
<th>value</th>
<th>value</th>
</tr>
</tbody>
</table>

我有下一个Knockout HTML模型allRoles这是带有动态标头的数组

<table>
            <thead>
                <tr data-bind="template: { name: 'tableHeader', foreach: allRoles, as: 'role',afterRender: addFirstColumn } ">                                                  

                </tr>
            </thead>    
                <tbody data-bind="foreach: {data: userRoles,as:'dep'}">
                <tr>
                    <td>
                       <span data-bind="text: dep.name"></span>
                    </td>                   
                    <td data-bind="foreach: {data: dep.roles, as: 'role'}">
                       <span data-bind="text: role.id"></span>
                    </td>
                </tr>
                </tbody>
            </table>


<script type="text/html" id="tableHeader">
    <th data-bind="text: role.name">

    </th>
</script>

我怎么能添加静态？

您可能正在寻找Knockout 的无容器控制流语法.它看起来像这样:

<table>
    <thead>
        <tr>
            <th>Static</th>
            <!-- ko foreach: allRoles -->
                <th data-bind="text: name"></th>
            <!-- /ko -->
        </tr>
    </thead>
</table>
