我的“会员”数据库中有3个表，其中包含有关其所属成员名称和团队的信息。我正在尝试构建2个插件。
One that lists all of my members, with the exception of a "master" member
which is a member of all teams. with the ability to bulk add or delete to
or from a team.
The second is a list of all teams, with the ability to bulk add or delete
to or from a members profile.
“members”具有成员名称。它还包含一个“主”成员，拥有所有团队的成员资格。它还包含其余成员。
“团队”包含所有团队信息
“members_team”包含成员的ID，并将这些ID连接到与团队关联的ID。每个团队协会一排。
我一直在试验我将在下面添加的现有代码。此时我甚至无法显示表格的内容，更不用说进入批量编辑了。当它与我的编辑一起运行时，我不断得到一个空表或错误。
