如何使QTableWidget的列占据最大空间？

from PyQt5.QtWidgets import QApplication, QTableWidget, QTableWidgetItem, QHeaderView

app = QApplication([])

table = QTableWidget()
table.setColumnCount(3)
table.setRowCount(5)

header = table.horizontalHeader()
header.setSectionResizeMode(QHeaderView.ResizeMode.Stretch)

for i in range(5):
    for j in range(3):
        table.setItem(i, j, QTableWidgetItem(f"Item {i+1}-{j+1}"))

table.show()
app.exec_()

from PyQt5.QtWidgets import QApplication, QTableWidget, QTableWidgetItem

app = QApplication([])

table = QTableWidget()
table.setColumnCount(3)
table.setRowCount(5)

for i in range(5):
    for j in range(3):
        table.setItem(i, j, QTableWidgetItem(f"Item {i+1}-{j+1}"))

table.resizeColumnsToContents()

table.show()
app.exec_()

from PyQt5.QtWidgets import QApplication, QTableWidget, QTableWidgetItem

app = QApplication([])

table = QTableWidget()
table.setColumnCount(3)
table.setRowCount(5)

for i in range(5):
    for j in range(3):
        table.setItem(i, j, QTableWidgetItem(f"Item {i+1}-{j+1}"))

table.setColumnWidth(0, 100)
table.setColumnWidth(1, 200)
table.setColumnWidth(2, 300)

table.show()
app.exec_()
