edit:

that's code have in base entity of plugin:

 public static function gettablename()     {         global $wpdb;          return $wpdb->base_prefix . static::$table;     } 

should change following in order support table per site?

 public static function gettablename() {     global $wpdb;      return $wpdb->prefix . static::$table; } 

if using $wpdb->prefix when creating tables, have separate tables each site.

global $wpdb; $my_table = $wpdb->prefix . 'my_table'; $query = "create table $my_table..."; 

the above code result in separate table each site, names wp_2_my_table, wp_3_my_table, etc (assuming using default base prefix wp_).

the majority of plugins not have updated support multi-sites explicitly, long adhere best practices.

conversely if wanted create single table of sites in network, use $wpdb->base_prefix.

just make sure consistently use correct prefix when creating or accessing tables.

if want separate tables each site, yes need change use $wpdb->prefix rather $wpdb->base_prefix. note if you're creating tables in activation hook, you'll have re-install plugin in order create new tables.
