So you want the contents of one cell be replaced continually? In that case, you have to use AJAX to retrieve your data and a timer to trigger this retrieval and contents change.

You don't have to use AJAX. You can put the content you want to refresh in an iframe, and the framed webpage will have a meta refresh header. This type of thing has been done for years before AJAX existed.

by using you can achieve

Algorithm :

1. Create the td with some id.
2. Send the ajax request( for require time of interval )
3. Get the random rows from by ajax , and put the values into that specific row id using innner.HTML
4. That's all it will work.
