如何在QTableWidget中仅获取包含值的行/列的数量？

# 获取仅包含值的行数
def getNonEmptyRowCount(tableWidget):
    rowCount = tableWidget.rowCount()
    nonEmptyRowCount = 0
    for row in range(rowCount):
        for column in range(tableWidget.columnCount()):
            item = tableWidget.item(row, column)
            if item is not None and item.text() != "":
                nonEmptyRowCount += 1
                break
    return nonEmptyRowCount

# 获取仅包含值的列数
def getNonEmptyColumnCount(tableWidget):
    columnCount = tableWidget.columnCount()
    nonEmptyColumnCount = 0
    for column in range(columnCount):
        for row in range(tableWidget.rowCount()):
            item = tableWidget.item(row, column)
            if item is not None and item.text() != "":
                nonEmptyColumnCount += 1
                break
    return nonEmptyColumnCount
