PyQt TableView将图标居中对齐

from PyQt5.QtCore import Qt
from PyQt5.QtGui import QIcon
from PyQt5.QtWidgets import QApplication, QTableView, QStyledItemDelegate

class IconDelegate(QStyledItemDelegate):
    def paint(self, painter, option, index):
        if index.data():
            icon = index.data()
            iconSize = option.rect.height() - 4
            icon.paint(painter, option.rect.left() + 2, option.rect.top() + 2, iconSize, iconSize, Qt.AlignCenter)
    
    def sizeHint(self, option, index):
        return option.rect.size()

app = QApplication([])
table = QTableView()
delegate = IconDelegate()
table.setItemDelegate(delegate)

# 添加数据和图标
table.setModel(your_model)
table.setColumnWidth(0, 100)  # 设置列宽
table.setRowHeight(0, 50)  # 设置行高

table.show()
app.exec_()
