如何 return 对象 jsx 中的变量

Question

查看带有 >>> 的问题行。目前的代码是这样的：

tableData() {
    const filteredEvents = this.props.graphData.events.filter((event) =>
      moment(event.eventDate).isBetween(this.startMoment, this.endMoment)
    );

    const eventsByM = _.groupBy(filteredEvents, (event) => event.metadata.mId);
    const tableRows = Object.values(eventsByM).map((events) => {
      const firstEvent = events[0];

      return ({
>>>     "Mentee Name": firstEvent.modalData.menteeName,
        "Mentor Name": firstEvent.modalData.mentorName,
        "Conversations Logged": events.length,
        tableRowUrl: firstEvent.modalData.tableRowUrl,
      });
    });
    return tableRows;
  }

我想将字符串“Mentee Name”设为变量，但 jsx 并未将其作为变量读取。我怎样才能做到这一点？我这样试过，但它的字面意思是“menteeName”：

tableData() {
    const filteredEvents = this.props.graphData.events.filter((event) =>
      moment(event.eventDate).isBetween(this.startMoment, this.endMoment)
    );

    const eventsByM = _.groupBy(filteredEvents, (event) => event.metadata.mId);
    const tableRows = Object.values(eventsByM).map((events) => {
      const firstEvent = events[0];
      const menteeName = "Apprentice name";

      return ({
 >>>    menteeName: firstEvent.modalData.menteeName,
        "Mentor Name": firstEvent.modalData.mentorName,
        "Conversations Logged": events.length,
        tableRowUrl: firstEvent.modalData.tableRowUrl,
      });
    });
    return tableRows;
  }

您可以像这样使用变量作为对象键：

[menteeName]: firstEvent.modalData.menteeName
