Thank so much.I can see your code so worked well.Thanks for the help.I will update with the other features.You have solved it.Thanks once again Azel_ErFurt and others.

The image I added is what I end up having.But,I need help on it.When I changed the quantity of product from 1 to another number, I want the table to update automatically.How can I do that?
My second interest is how can I make multiple users to operate the UI simultaneously.

This is function I used;

    def your_function(self):
        self.row = self.Products_table.currentRow()
        self.currentproduct = (self.Products_table.item(self.row, 0).text() )
        self.currentprice = (self.Products_table.item(self.row,1).text() )
        ordereditems = QtGui.QTableWidgetItem()
        row = self.ordereditems.currentRow()
        numRows = self.ordereditems.rowCount()
        self.ordereditems.insertRow(numRows)
        self.total = 0.0
        self.items ={}
        self.ordereditems.setItem(numRows, 0, QtGui.QTableWidgetItem(self.currentproduct))
        self.ordereditems.setItem(numRows, 1, QtGui.QTableWidgetItem(str(self.currentprice)))
        self.ordereditems.setItem(numRows, 2, QtGui.QTableWidgetItem("1"))
        for numRows in range(numRows+1):
            self.ordereditems.setItem(numRows, 2, QtGui.QTableWidgetItem(str(self.currentquantity)))
            self.currentprice =float(self.ordereditems.item(numRows,1).text() )
            amount = float(self.currentprice) * float(self.currentquantity)
            self.ordereditems.setItem(numRows, 3, QtGui.QTableWidgetItem(str(amount)))
            self.total += amount
        self.totallinedit.setText(str(self.total))
        self.items = {str(self.currentproduct):self.currentquantity}
        self.items.update({str(self.currentproduct):self.currentquantity})
