标签: python pyqt xls qtablewidget

所以,我有一个QTableWidget,我想用xlwt模块将它保存到.xls文件...

以下是代码:

def savefile(self):
        filename = unicode(QtGui.QFileDialog.getSaveFileName(self, 'Save File', '', ".xls(*.xls)"))    
        wbk = xlwt.Workbook()
        self.sheet = wbk.add_sheet("sheet")
        self.row = 0
        self.col = 0
        self.add2(self.row, self.col)
        wbk.save(filename)    


def add2(self, row, col):
    for i in range(self.tableWidget.columnCount()):
        for x in range(self.tableWidget.rowCount()):
            try:
                teext = str(self.tableWidget.item(row, col).text())
                self.sheet.write(row, col, teext)
                row += 1
            except AttributeError:
                pass                   
        col += 1

但是,它只写出来自单元格0,0的文本,而没有其他内容......

我认为我犯了一些严重的错误......

更新

def savefile(self):
        filename = unicode(QtGui.QFileDialog.getSaveFileName(self, 'Save File', '', ".xls(*.xls)"))    
        wbk = xlwt.Workbook()
        self.sheet = wbk.add_sheet("sheet", cell_overwrite_ok=True)
        self.add2()
        wbk.save(filename)    


def add2(self):
    row = 0
    col = 0         
    for i in range(self.tableWidget.columnCount()):
        for x in range(self.tableWidget.rowCount()):
            try:             
                teext = str(self.tableWidget.item(row, col).text())
                self.sheet.write(row, col, teext)
                row += 1
            except AttributeError:
                row += 1
        row = 0
        col += 1

您可能还会发现使用范围(或xrange)的输出作为tableWidget.item调用的索引更简洁,更容易,而不是担心增加自己的计数器。您可能在代码中的其他位置使用工作表本身,但如果不是,则会节省一些内存,以便不将工作表指定为您的类的属性变量:

def savefile(self):
    filename = unicode(QtGui.QFileDialog.getSaveFileName(self, 'Save File', '', ".xls(*.xls)"))    
    wbk = xlwt.Workbook()
    sheet = wbk.add_sheet("sheet", cell_overwrite_ok=True)
    self.add2(sheet)
    wbk.save(filename)

def add2(self, sheet):
    for currentColumn in range(self.tableWidget.columnCount()):
        for currentRow in range(self.tableWidget.rowCount()):
            try:
                teext = str(self.tableWidget.item(currentRow, currentColumn).text()
                sheet.write(currentRow, currentColumn, teext)
            except AttributeError:
                pass

因为您正在使用range命令,所以currentColumn变量将从0递增到columnCount(),currentRow将从0递增到currentRow()
