Highlighting Part Of Table When A Hotspot Is Clicked?

I'm working on asomething that has an image map with multiple hotspots. When the hotspot is clicked, I need it to highlight a particular row in the table that gives information about the person that was clicked on.

I know how to highlight the row using the BackColor part like I did here:

<asp:Table ID="Table1" runat="server" border="1">
<asp:tablerow BackColor="LightBlue">
<asp:tablecell>
<B>Instructor Name</B>
</asp:tablecell>
<asp:tablecell>
<B>Certification Level</B>
</asp:tablecell>
</asp:tablerow>

But how can I use it in this part of the code??:

protected void instructor_Clicked(object sender, ImageMapEventArgs e)
{
switch (e.PostBackValue)
{
case "Jardina":
**Need to highlight Row1 in the table here**
break;
