jQuery related item table highlighter

I have a table fill with cell items.

If I click on a cell item, that cell item is 'li开发者_如何学运维nked' or related to other cell items, which need to be highlighted.

If another cell item is clicked, that cell's related cells need to light up.

Is there a jQuery plugin to accomplish something like this? Or would I have to look into writing one myself?

Try the jQuery UI Selectable plugin.
