vue使用过滤改变el-switch开关的状态

需求：

每个小组只能有一个组长，当打开开关设置组长时候，其他的组长一列为否状态

setupLeader(row, event){   
        console.log(row, event, '设置组长开关')
        this.$axios({
            method: 'get',
            url: this.saveThousandCheckGroupLeader,
            params:  {
                userId: row.userId,
                groupId: row.groupId
            }
        }).then((res) => { 
           let id = row.id;
           console.log(id);
           this.tableData.forEach(item => {
                if (row.userId == item.userId)  {
                    row.isLeader = item.isLeader;
                }
            });       
            this.tableData.filter((val) => {
                return val.id != row.id;
            })
            this.getCheckGroupUserExList();
        }) 
    },
