这样做的本机方式是扩展类WP_List_Table并让 WordPress 处理表格显示的所有细节。我从kaiser的插件Internal Link Check知道这一点。下面的示例是一个剥离版本，它执行一个非常简单的 SQL 查询。
首先，我们需要一个帮助页面（使用 PHP5.3+ 匿名函数）：
add_action('admin_menu', function()
{
add_menu_page(
'TE',
'<span style="color:#e57300;">Table Example</span>',
'edit_pages',
'table-example',
function() {
echo '<div class="wrap">';
screen_icon('edit');
echo '<h2>Table Example</h2>';
new B5F_WP_Table();
echo '</div>';
},
'http://sstatic.net/stackexchange/img/favicon.ico',
1 // create before Dashboard menu item
);
});
这是最终结果：
这里是执行所有操作的类（注意需要导入主类）。您必须调整数据的查询和表列。
if( is_admin() && !class_exists( 'WP_List_Table' ) )
require_once( ABSPATH . 'wp-admin/includes/class-wp-list-table.php' );
