Python 3 – PyQtでテーブルを使用する方法

data = {'col1':['1','2','3','4'],
        'col2':['1','2','1','3'],
        'col3':['1','1','2','1']}

     
from PyQt5.QtWidgets import QMainWindow, QApplication, QWidget, QAction, QTableWidget,QTableWidgetItem,QVBoxLayout
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot
import sys

data = {'col1':['1','2','3','4'],
        'col2':['1','2','1','3'],
        'col3':['1','1','2','1']}
 
class TableView(QTableWidget):
    def __init__(self, data, *args):
        QTableWidget.__init__(self, *args)
        self.data = data
        self.setData()
        self.resizeColumnsToContents()

                newitem = QTableWidgetItem(item)
                self.setItem(m, n, newitem)
        self.setHorizontalHeaderLabels(horHeaders)
 
def main(args):
    app = QApplication(args)
    table = TableView(data, 4, 3)
    table.show()
    sys.exit(app.exec_())
 
if __name__=="__main__":
    main(sys.argv)
