        <th>Text</th>
    </tr>
    <%= @articles.each do |article| %>
    <tr>

        <td><%= article.title %></td>
        <td><%= article.text %></td>
        <td><%= link_to 'show', article_path(article) %></td>
        <td><%= link_to 'new', new_article_path %></td>
        <td><%= link_to'edit', edit_article_path(article) %></td>

    </tr>
<% end %>
</table>

我只需要显示文章列表。我怎么能在这里删除数组。这里我只显示不包含数组的文章列表。

提前致谢
