from PyQt5.QtWidgets import QApplication, QMainWindow, QTableView, QHeaderView
from PyQt5.QtSql import QSqlDatabase, QSqlTableModel

app = QApplication([])
window = QMainWindow()

db = QSqlDatabase.addDatabase("QSQLITE")
db.setDatabaseName("your_database_name.db")
db.open()

table_view = QTableView(window)

model = QSqlTableModel(window)
model.setTable("your_table_name")
model.select()
table_view.setModel(model)

header = table_view.horizontalHeader()
header.setSectionResizeMode(QHeaderView.ResizeToContents)
header.setSectionsClickable(True)
header.setSortIndicatorShown(True)

window.setCentralWidget(table_view)
window.show()
