写一段pyqt将excel表转化为表格控件的代码，并设置跨行

下面是将Excel表转化为表格控件并设置跨行的PyQt代码：

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QTableWidget, QTableWidgetItem
from openpyxl import load_workbook

class ExcelTable(QMainWindow):
    def __init__(self, filename):
        super().__init__()
        self.filename = filename
        self.initUI()

    def initUI(self):
        self.tableWidget = QTableWidget()
        self.setCentralWidget(self.tableWidget)

        # 加载Excel文件
        wb = load_workbook(filename=self.filename)
        ws = wb.active

        # 获取表格尺寸
        rows = ws.max_row
        cols = ws.max_column

        # 设置表格行数和列数
        self.tableWidget.setRowCount(rows)
        self.tableWidget.setColumnCount(cols)

        # 读取Excel数据并填充表格
        for row in range(1, rows+1):
            for col in range(1, cols+1):
                cell = ws.cell(row=row, column=col)
                item = QTableWidgetItem(str(cell.value))
                self.tableWidget.setItem(row-1, col-1, item)

        # 设置跨行
        for row in range(1, rows+1):
            for col in range(1, cols+1):
                cell = ws.cell(row=row, column=col)
                rowspan = cell.rowspan
                if rowspan > 1:
                    for i in range(1, rowspan):
                        self.tableWidget.setItem(row+i-2, col-1, QTableWidgetItem(''))

        self.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = ExcelTable('example.xlsx')
    sys.exit(app.exec_())

这段代码通过使用openpyxl模块来加载Excel文件，并将其数据填充到QTableWidget控件中。在读取每个单元格时，如果单元格有跨行属性，则根据跨行属性在表格中插入空白单元格。
