Inserting and a space using the DOM

I'm working on customer management system, and have introduced a little AJAX to make the interface a bit more user friendly. At the moment, I'm having a little trouble with an edit-in-place contact controller.

For adding a new contact to a customer's file I have a form which when filled out saves the contact to the database synchronously then removes the form and shows the new contact details as text. It's not the AJAX part that is causing me a problem, the application is fully functional, it's more a matter of presenting the new details neatly on the page after they have been saved.

        newContactTr1 = document.createElement('tr');
        newContactL1 = document.createElement('td');
        newContactR1 = document.createElement('td');
        newContactL1.style.fontWeight = 'bold';
        newContactR1.style.fontWeight = 'bold';

        newContactTr2 = document.createElement('tr');
        newContactL2 = document.createElement('td');
        newContactR2 = document.createElement('td');

        linebreak = document.createElement('br');
        space = document.createTextNode(' ');

        newContactTr1.id = 'row1-NewContactTemp';
        newContactTr2.id = 'row2-NewContactTemp';
        newContactL2.id = 'numbers-NewContactTemp';
        newContactR2.id = 'address-NewContactTemp';

        newContactL1.appendChild(fnameSpan);
        newContactL1.appendChild(space);
        newContactL1.appendChild(lnameSpan);
        newContactR1.appendChild(document.createTextNode('Address'));
        newContactL2.appendChild(phone1Span);
        newContactL2.appendChild(space);
        newContactL2.appendChild(phone1descSpan);
        newContactL2.appendChild(linebreak);
        newContactL2.appendChild(phone2Span);
        newContactL2.appendChild(space);
        newContactL2.appendChild(phone2descSpan);
        newContactL2.appendChild(linebreak);
        newContactL2.appendChild(phone3Span);
        newContactL2.appendChild(space);
        newContactL2.appendChild(phone3descSpan);
        newContactR2.appendChild(street1Span);
        newContactR2.appendChild(linebreak);
        newContactR2.appendChild(street2Span);
        newContactR2.appendChild(space);
        newContactR2.appendChild(townSpan);
        newContactR2.appendChild(linebreak);
        newContactR2.appendChild(countySpan);
        newContactR2.appendChild(linebreak);
        newContactR2.appendChild(postcodeSpan);

        newContactTr1.appendChild(newContactL1);
        newContactTr1.appendChild(newContactR1);
        newContactTr2.appendChild(newContactL2);
        newContactTr2.appendChild(newContactR2);

        contactsTable = document.getElementById('contactsTable');
        contactsTable.appendChild(newContactTr1);
        contactsTable.appendChild(newContactTr2);
