Hi,
I am trying to extract all items of my table and stream to txt file.
This is what I have done
Qt Code: 
  1. QFile file("/home/ramraj/Desktop/bill.txt");
  2.     if (!file.open(QIODevice::WriteOnly | QIODevice::Text))
  3.          qDebug()<<"file not open";
  4.  
  5.        QTextStream out(&file);
  6.        QString companyName=ui->companyName->text();
  7.        QString companyAddress=ui->addressLabel_2->text();
  8.        QString companyPhone=ui->phoneLabel_2->text();
  9.        QString companyEmail=ui->emailLabel_2->text();
  10.        QString companyVAT=ui->vatLabel_2->text();
  11.  
  12.        out <<"                                       "<<companyName<<endl;
  13.        out <<"                                       "<<companyAddress<<endl;
  14.        out <<"                                       "<<companyPhone<<","<<companyEmail<<endl;
  15.        out <<"                                       "<<"VAT No.:"<<companyVAT<<endl;
  16.        out <<"                                       "<<"ABBREVIATED TAX INVOICE"<<endl;
  17.        out <<endl<<endl;
  18.        out <<"Bill # :"<<endl;
  19.        out <<"Date   :"<<ui->currentDate->text()<<endl;
  20.        out<<"Payment Mode: Cash"<<endl;
  21.        out <<"-----------------------------------------------------------------------------------------------------------"<<endl;
  22.        out <<"ID\t" <<"Particulars\t\t\t"<<"Rate\t\t"<<"Quantity\t"<<"Amount"<<endl;
  23.        out <<"-----------------------------------------------------------------------------------------------------------"<<endl;
  24.        QString textData;
  25.        int rows = ui->billTable->rowCount();
  26.        int columns = ui->billTable->columnCount();
  27.        for (int i = 0; i < rows; i++) {
  28.            for (int j = 0; j < columns; j++) {
  29.  
  30.                    textData += ui->billTable->item(i,j)->text();
  31.                    textData += "\t\t";
  32.            }
  33.            textData += "\n";
  34.  
  35.        }
  36.        out<<textData<<endl;
  37.        out<<"---------------------------------------------------------------------------------------------------------------"<<endl;
  38.        out<<"                                                               "<<"Total:"<<ui->subTotal_2->text()<<endl;
To copy to clipboard, switch view to plain text mode 


But,I am unable to get good alignment.
Here is what I have got:
