How to reRender only particular row(s) of datatable

[meenak]

I have a datatable iterated on a variable.Each loop produces two textareas (text entered in first one should appear in the second clearing the text in the first one).The user may enter text into some of the textareas and when he clicks on update only the textarea(s) containig text and their corresponding textarea(s) should be reRendered.
how to do this using reRender in commandLink , outputPanel or is there any other way out.
thanks in advance

if you use rich:dataTable then you may use ajaxKeys attribute to bind the rowKeys to be reRendered there. After you need to point reRender on the whole table and only specified rows will be reRedered

Can you post an example please?

dataTable fully based on a4j:repeat component. So you may take a look to the a4j:repeat reRendering example:
