使用 CSS 隐藏表格中的列

Question

我想隐藏下表中的一些列。它来自 wordpress 插件，因此 id 和类是预定义的。我希望我可以用 css fx: display:none 解决它，但我似乎无法让它工作。

<table cellspacing="0" class="wp-list-table widefat fixed brugere">
    <thead>
        <tr>
            <th class="manage-column column-company_name sortable asc" id="company_name" scope="col" style="">
                <a href="http://xxx.xxx.dk/xxx/?orderby=company_name&amp;order=desc"><span>Virksomhed</span><span class="sorting-indicator"></span></a>
            </th>
            <th class="manage-column column-CVR._Nr." id="CVR._Nr." scope="col" style="">CVR. Nr.</th>

Answer 1

尝试添加一个单独的 .CSS（并在脑海中最后调用这个 .CSS），例如尝试

#company_name {
display: none; //If it doesn't work try visibility: hidden;
}

Answer 2

您可以在 CSS 中使用 nth-child 选择器来隐藏您需要的列。但在这种情况下，您也需要隐藏相同的 th。

CSS：

table tr th:nth-child(1), table tr td:nth-child(1){
 display:none;// It will hide the first column of the table
}
