QTcpsocket/QTcpserver传输，如何使用QdataStream传输一个表数据？？

有思路：在每一行写数据流，然后调用write()，但是怎么再写呢？

存在问题：数据乱码，第一行数据重复写入。

从fh文件中提取保存的数据流数据，写self.block进行TCP传输（数据以表格每一行的格式保存，读出行数和列表数据）->不能正常显示求例子或想法，用 PYQT5 编写

服务器代码：

self.block = QByteArray()
fh = QFile(name)
        fh.open(QIODevice.ReadOnly)
        tableData = QDataStream(fh)        # Get Data from File
        tableData.setVersion(QDataStream.Qt_5_6)

        stream = QDataStream(self.block, QIODevice.WriteOnly)    # Input data to socket
        stream.setVersion(QDataStream.Qt_5_6)    
        self.clientConnection = self.server.nextPendingConnection()    


        while not tableData.atEnd():
            num,table=0,''
            num = tableData.readUInt16()
            table = tableData.readQStringList()

            stream.writeUInt16(0)
            stream.writeUInt16(num)
            stream.writeQStringList(table)
            stream.device().seek(0)
            stream.writeUInt16(self.block.size() - SIZEOF_INT16)  #
            self.clientConnection.write(self.block)
            self.clientConnection.flush()

客户端.py

def readMessage(self):
    try:

        print('readmessage')

        stream = QDataStream(self.socket)
        stream.setVersion(QDataStream.Qt_5_6)
        while not stream.atEnd():

            if self.blockSize == 0:

                if self.socket.bytesAvailable()<SIZEOF_UINT16:

                    return
                self.blockSize = stream.readUInt16()

            if self.socket.bytesAvailable()<self.blockSize:

                return
            num=stream.readUInt16()
            message = stream.readQStringList()      #?????????

            print(num,message)
            if num<1:

                self.tableWidget.setRowCount(1) # First row Data
                for a in range(0, 11):
                    # print(a)
                    newItem = QTableWidgetItem(message[a])
                    self.tableWidget.setItem(0, a, newItem)
            else:
                self.tableWidget.insertRow(0)
                for a in range(0, 11):                      
                    newItem = QTableWidgetItem(message[a])
                    self.tableWidget.setItem(0, a, newItem)
        print('closee')
        self.socket.disconnect()
        self.socket.close()

    except:
        self.socket.close()
