感谢 reduce函数学会了

const taskgrouplist = data.reduce((result, item) => {
    const existingGroup = result.find(group => group.sid === item.rwzid);
    if (existingGroup) {
        existingGroup.taskLists.push({
            sid: item.rwid,
            groupid: item.rwzid,
            taskName: item.rwmc
        });
    } else {
        result.push({
            sid: item.rwzid,
            groupName: item.rwzmc,
            taskLists: [{
                sid: item.rwid,
                groupid: item.rwzid,
