RT，如何用essentials的配置文件使tab列表显示玩家的prefix和suixff

# A color code between 0-9 or a-f. Set to 'none' to disable.
ops-name-color: 'c'

# The character(s) to prefix all nicknames, so that you know they are not true usernames.
nickname-prefix: '~'

# The maximum length allowed in nicknames. The nickname prefix is included in this.
max-nick-length: 18

# Disable this if you have any other plugin, that modifies the displayname of a user.
change-displayname: false

# When this option is enabled, the (tab) player list will be updated with the displayname.
# The value of change-displayname (above) has to be true.
change-playerlist: false

# When essentialschat.jar isn't used, force essentials to add the prefix and suffix from permission plugins to displayname.
# This setting is ignored if essentialschat.jar is used, and defaults to 'true'.
# The value of change-displayname (above) has to be true.
# Do not edit this setting unless you know what you are doing!
add-prefix-suffix: false

不是要用ess的权限组的插件吗

我也有，请问怎么改

/mangaddv XXX prefix &1 设置用户组XXX的prefix变量为&1；
