qtablewidget单元格内容设置左对齐

可以使用QTableWidgetItem的setTextAlignment()方法设置单元格内容的对齐方式。示例代码如下：

from PyQt5.QtWidgets import QTableWidget, QTableWidgetItem, QApplication, QHBoxLayout, QWidget
from PyQt5.QtCore import Qt

app = QApplication([])
table_widget = QTableWidget()
table_widget.setRowCount(2)
table_widget.setColumnCount(2)

for row in range(table_widget.rowCount()):
    for column in range(table_widget.columnCount()):
        item = QTableWidgetItem()
        item.setText(f"({row}, {column})")
        item.setTextAlignment(Qt.AlignLeft) # 设置对齐方式为左对齐
        table_widget.setItem(row, column, item)

layout = QHBoxLayout()
layout.addWidget(table_widget)

widget = QWidget()
widget.setLayout(layout)
widget.show()

app.exec_()

运行结果如下图所示：
