how to keep the appearance effect of hyperlink,but don't jump to another link when click on cell

Hello Leon,
 
You can try to apply following CSS to a span

text-decoration: underline;
cursor: pointer;

Or you can use regular links and prevent default behavior in the JavaScript handler:

function onLinkClick(e) {
 e.stopImmediatePropagation();
 // your code
}

Hope it helps.
 
Regards,
Ian
