为了让球滚动，我使用这个sitepoint template将一个自定义表放在一个管理选项页面上的插件中...到目前为止一直很好，但是插件的设计是为了生活在它的自己的页面...事情是我需要它存在于现有的页面上...虽然我试图将代码移动到特定的文件但它似乎根本没有。当然还有更多代码，我只是列出了在管理菜单中创建菜单页面的相关部分....所以我问如何将其添加到现有页面/操作中而不是创建新页面？

用于初始化插件的管理页面的代码：
add_action('load_admin_faucet_page', 'plugin_settings_page');
function faucet_admin_page_container(){
require '../../../myfolder/myfile.php';
}
从那时起，我认为它将变得如此简单：
add_action('load_admin_faucet_page', 'plugin_settings_page')
但是......没有骰子，我们在这里。
编辑1：根据要求，这是我 尝试加载myfile.php的整个受影响的代码部分（不是所有内容，只是扩展wp_list_table的类 - 我会保留操作现在的主要插件文件）...现在我只是试图将它保存在主插件文件上并将其加载到该特定页面上。
