Floating navigation bar

[calista]

I have a vertical format navigation bar that is in a nested table. How do I get it to float as the user scrolls up and down the document? Here is the table:
<td valign=&quot;top&quot; style=&quot;position:relative;float:top;&quot;>
<table width=&quot;46&quot; border=&quot;0&quot;>
<tr>
<td><a href=&quot;New Web Page/Home.htm&quot;><img border=&quot;0&quot; src=&quot;Images/Tabs/Tab%20Home.png&quot;></a></td>
</tr>
<tr>
<td><a href=&quot;#SummaryGraph&quot;><img border=&quot;0&quot; src=&quot;Images/Tabs/Tab%20Summary.png&quot;></a></td>
</tr>
<tr>
<td><a href=&quot;#WorkHistory1&quot;><img border=&quot;0&quot;src=&quot;Images/Tabs/Tab%20Work1.png&quot;></a></td>
</tr>
<tr>
<td><a href=&quot;#WorkHistory2&quot;><img border=&quot;0&quot;src=&quot;Images/Tabs/Tab%20Work2.png&quot;></a></td>
</tr>
<tr>
<td><a href=&quot;#SelfAppraisal&quot;><img border=&quot;0&quot; src=&quot;Images/Tabs/Tab%20Self%20App.png&quot;></a></td>
</tr>
<tr>
<td><a href=&quot;#FutRView&quot;><img border=&quot;0&quot;src=&quot;Images/Tabs/Tab%20FutRView.png&quot;></a></td>
</tr>
<tr>
<td><a href=&quot;#FocusedQuestions&quot;><img border=&quot;0&quot; src=&quot;Images/Tabs/Tab%20Focused.png&quot;></a></td>
</tr>
<tr>
<td><a href=&quot;#Resume&quot;><img border=&quot;0&quot; src=&quot;Images/Tabs/Tab%20Resume.png&quot;></a></td>
</tr>
</table>
</td>
