用列表加载Qtablewidget
用列表加载Qtablewidget
提问于 2019-02-14 13:31:22
我有一份清单如下
[('John', datetime.datetime(2019, 5, 5, 0, 54), datetime.datetime(2019, 5, 26, 22, 51, 36)),
('Rex', datetime.datetime(2019, 5, 26, 22, 51, 36), datetime.datetime(2019, 6, 15, 10, 22, 48)),
('Watson', datetime.datetime(2019, 6, 15, 10, 22, 48), datetime.datetime(2019, 7, 8, 13, 33, 36)),
('Manila', datetime.datetime(2019, 7, 8, 13, 33, 36), datetime.datetime(2019, 7, 29, 6, 18)),
('Pete', datetime.datetime(2019, 7, 29, 6, 18), datetime.datetime(2019, 8, 6, 18, 50, 24)),
('Mathew', datetime.datetime(2019, 8, 6, 18, 50, 24), datetime.datetime(2019, 8, 31, 3, 14, 24))]我创建了一个类似于Qtablewidget下面的UI
如何在Name列中添加名称，在From列中添加第一次日期，在To列中添加第二次日期。我尝试了按一下按钮上的setitem，但是没有工作。
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
import datetime
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.tableWidget = QtWidgets.QTableWidget(self.centralwidget)
self.tableWidget.setGeometry(QtCore.QRect(30, 90, 311, 301))
self.tableWidget.setObjectName("tableWidget")
self.tableWidget.setColumnCount(3)
self.tableWidget.setRowCount(0)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(0, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(1, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(2, item)
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(240, 430, 75, 23))
self.pushButton.setObjectName("pushButton")
MainWindow.setCentralWidget(self.centralwidget)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
item = self.tableWidget.horizontalHeaderItem(0)
item.setText(_translate("MainWindow", "Name"))
item = self.tableWidget.horizontalHeaderItem(1)
item.setText(_translate("MainWindow", "From"))
item = self.tableWidget.horizontalHeaderItem(2)
item.setText(_translate("MainWindow", "To"))
self.pushButton.setText(_translate("MainWindow", "Load"))
self.pushButton.clicked.connect(self.onload)
def onload(self):
for i in mainlist:
self.tableWidget.setItem(i[1])
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())我怎样才能让这件事成功

基本上这就像处理2D数组
- 获取数据的行数和列数： numcols = len(data) #(获取列数，第一行中的值计数(第一行是数据))numrow=len(数据)#(以获取数据中的行数、值数(即数组))
- 设置QTableWidget的尺寸： self.tableWidget.setColumnCount(numcols) self.tableWidget.setRowCount(数字)
- 使用basic nasted for循环传递数据(2D数组)：在每一步中，将数据(2D数组)中的值设置为QTableWidget中的相同位置： Self.tableWidget.setItem(行、列、QTableWidgetItem((数据) 其中：
- row, column = indexes in QTableWidget
- QTableWidgetItem((data[row][column])) = value which you will set in QTableWidget
备注： QTableWidgetItem(const QString &text)
QTableWidgetItem类提供与QTableWidget类一起使用的项。
注意:不能将日期时间传递给QTableWidgetItem，因为需要检查试图设置为QTableWidget的值是否为datetime，如果是，则需要将datetime转换为string：
if isinstance(data[row][column], datetime.datetime):
...data[row][column].strftime('%d/%m/%Y %H:%M:%S')完整代码：
from PyQt5.QtWidgets import QTableWidgetItem
from datetime import datetime
import datetime
data = [('John', datetime.datetime(2019, 5, 5, 0, 54), datetime.datetime(2019, 5, 26, 22, 51, 36)),
('Rex', datetime.datetime(2019, 5, 26, 22, 51, 36), datetime.datetime(2019, 6, 15, 10, 22, 48)),
('Watson', datetime.datetime(2019, 6, 15, 10, 22, 48), datetime.datetime(2019, 7, 8, 13, 33, 36)),
('Manila', datetime.datetime(2019, 7, 8, 13, 33, 36), datetime.datetime(2019, 7, 29, 6, 18)),
('Pete', datetime.datetime(2019, 7, 29, 6, 18), datetime.datetime(2019, 8, 6, 18, 50, 24)),
('Mathew', datetime.datetime(2019, 8, 6, 18, 50, 24), datetime.datetime(2019, 8, 31, 3, 14, 24))]
numrows = len(data) # 6 rows in your example
numcols = len(data[0]) # 3 columns in your example
# Set colums and rows in QTableWidget
self.tableWidget.setColumnCount(numcols)
self.tableWidget.setRowCount(numrows)
# Loops to add values into QTableWidget
for row in range(numrows):
for column in range(numcols):
# Check if value datatime, if True convert to string
if isinstance(data[row][column], datetime.datetime):
self.tableWidget.setItem(row, column, QTableWidgetItem((data[row][column].strftime('%d/%m/%Y %H:%M:%S'))))
else:
self.tableWidget.setItem(row, column, QTableWidgetItem((data[row][column])))结果：
