Can anybody please help me.

AJAX can do that for you. Give your table an ID and in a javascript grab the table object and loop through the children (i.e. rows) and make them visible or hidden as you go through them. If you have more specific requirements (i.e. start at certain row clicked on) you might want to check out (google) rowIndex. I'm sure you'll get other responses in here that are more efficient but that's how I would do it if I had to right now. Hope it helps.

Ajax really isn't necessary. It's really just a matter of using the display CSS property appropriately.

Ajax would only be necessary if one wishes to delay the fetching of the hidden data until it is required. In that case, Ajax is indispensable.
