PyQt:QTableWidget到.xls文件

Question

所以,我有一个QTableWidget,我想使用xlwt模块将其保存到.xls文件中...

这是代码:

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,这只写出了来自单元格0,0的文本而没有别的......

我想我犯了一些严重错误......

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             

解决了这个问题......

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，而不必担心增加自己的计数器。您可能会在代码中的其他位置使用工作表本身，但如果没有，则不将工作表分配为类的属性变量会节省一些内存：

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

因为您使用的是 range 命令，所以 currentColumn 变量将从 0 递增到 columnCount()，currentRow 将从 0 递增到 currentRow()
