How to split header | Header into tow column Header

I am giving very powerful tecknique to split the header into tow column.
Find and  these lines of code:

<b:section class=’header’ id=’header’ maxwidgets=’1′ showaddelement=’no’>
<b:widget id=’Header1′ locked=’true’ title=’Forum (Header)’ type=’Header’/>
</b:section>

Then replace above code by the below code code:

<!– HEADER EDITED START–>
<table><tr><td>
<b:section class=’header’ id=’header’ maxwidgets=’1′ showaddelement=’no’>
<b:widget id=’Header1′ locked=’true’ title=’Header’ type=’Header’/>
</b:section></td>
<td style=”width: 510px;”>
<b:section class=’header’ id=’header2′ maxwidgets=’1′ showaddelement=’yes’/>
</td></tr></table>
<!– HEADER EDITED END–>
