你能精确地回答你的问题吗？是否要为来自同一网络的多个Wordpress站点创建一个表？如果在安装时使用插件代码创建表，请使用$wpdb->prefix.“tablename”，这样，当某个站点的插件处于活动状态时，该表将自动为该站点创建。在这些表中插入数据时，请使用$wp->前缀。这应该符合你的目的。@AbhisekMalakar这也能解决如何为每个网络站点创建每个表的问题吗？你能精确地回答你的问题吗？是否要为来自同一网络的多个Wordpress站点创建一个表？如果在安装时使用插件代码创建表，请使用$wpdb->prefix.“tablename”，这样，当某个站点的插件处于活动状态时，该表将自动为该站点创建。在这些表中插入数据时，请使用$wp->前缀。这应该符合你的目的。@AbhisekMalakar这也能解决如何为每个网络站点创建每个表的问题吗？
