pyqt5 QTableWidget 不会显示 PyEve 数据集中的 id 键值

Question

我正在尝试构建一个 pyqt5 小部件来显示来自 PyEve 的数据集，但我无法将 id 键值显示到 table 行 header 中。这是生成 QTableWidget

的代码部分

http = "http://127.0.0.1:5000/people"
con = requests.get(http)

self.tview = QTableWidget()
self.tview.setRowCount(len(con.json()['_items']))
self.tview.setColumnCount(2)

self.tview.setHorizontalHeaderItem(0, QTableWidgetItem("Firstname"))
self.tview.setHorizontalHeaderItem(1, QTableWidgetItem("Lastname"))

row = 0
for item in con.json()['_items']:
    self.tview.setVerticalHeaderItem(row, QTableWidgetItem(item["id"]))
    self.tview.setItem(row, 0, QTableWidgetItem(item['firstname']))
    self.tview.setItem(row, 1, QTableWidgetItem(item['lastname']))
    row += 1

结果： QTableWidget

这是 API 在 shell

中调用的数据集

    $ http localhost:5000/people

这是我从 python 控制台得到的输出，用于打印 "id" 值

import requests 
r = requests.get('http://127.0.0.1:5000/people') 
for i in r.json()["_items"]: print(i["id"])
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

我也试过在verticalHeader外显示ID号，但无济于事

任何见解都会非常有帮助，在此先感谢

如@eyllanesc 所说.. 将其更改为

self.tview.setVerticalHeaderItem(row, QTableWidgetItem(str(item["id"])))

成功了。谢谢
