【中文标题】pyqt5 QTableWidget 不会显示来自 PyEve 数据集的 id 键值【英文标题】：pyqt5 QTableWidget won't display id key value from PyEve dataset 【发布时间】：2017-11-17 07:26:18 【问题描述】：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 键值显示到表行标题中。这是生成 QTableWidget 的部分代码
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
这是来自 shell 中 API 调用的数据集

这是我从 python 控制台打印“id”值的输出
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
我也尝试在verticalHeader之外显示ID号，但无济于事
任何见解都会非常有帮助，在此先感谢
【问题讨论】：
更改为self.tview.setVerticalHeaderItem(row, QTableWidgetItem(str(item["id"])))
【参考方案1】：
正如@eyllanesc 所说.. 将其更改为
self.tview.setVerticalHeaderItem(row, QTableWidgetItem(str(item["id"])))
成功了。谢谢

以上是关于pyqt5 QTableWidget 不会显示来自 PyEve 数据集的 id 键值的主要内容，如果未能解决你的问题，请参考以下文章
