根据Tim Malone给出的答案，我有以下工作代码：

 /* Activate Hook Plugin */
    register_activation_hook(__FILE__, \'ulh_add_user_logins_table\');

    /* call when plugin is activated */
    function ulh_add_user_logins_table() {
        global $wpdb;
        $charset_collate = $wpdb->get_charset_collate();
            $fa_user_logins_table = $wpdb->prefix . "fa_user_logins";

        $sql = "CREATE TABLE $fa_user_logins_table (
             id int(11) NOT NULL AUTO_INCREMENT,
       user_id int(11) ,
      `time_login` datetime NOT NULL,
      `time_logout` datetime NOT NULL,
      `ip_address` varchar(20) NOT NULL,
      `browser` varchar(100) NOT NULL,
      `operating_system` varchar(100) NOT NULL,
      `country_name` varchar(100) NOT NULL,
      `country_code` varchar(20) NOT NULL   ,                             
       PRIMARY KEY (`id`)
        ) $charset_collate;";

        require_once( ABSPATH . \'wp-admin/includes/upgrade.php\' );
        dbDelta( $sql );
            update_option( \'fa_userloginhostory_version\', \'1.0\' );
            ulh_update_tables_when_plugin_updating();
    }


    //call when plugin is updated. 
//Actually it gets called every time 
//but the sql query execute only when there is plugin version difference
    function ulh_update_tables_when_plugin_updating() {
        global $wpdb;
            $oldVersion = get_option( \'fa_userloginhostory_version\', \'1.0\' );
            $newVersion = \'1.2\';

            if ( !(version_compare( $oldVersion, $newVersion ) < 0) ) {
                return FALSE;
            }

        $charset_collate = $wpdb->get_charset_collate();
            $fa_user_logins_table = $wpdb->prefix . "fa_user_logins";

        $sql = "CREATE TABLE $fa_user_logins_table (
             id int(11) NOT NULL AUTO_INCREMENT,

      `time_logout` datetime NOT NULL,

        dbDelta( $sql );
        update_option( \'fa_userloginhostory_version\', $newVersion );
    }

    add_action(\'init\', \'ulh_update_tables_when_plugin_updating\');
