( please find highlighted lines for modified code.)

you just give id to your table rows then,
in your java script you can know which row is clicked like this:

function buttonPress(str,x)
{
    var table = document.getElementById('test');   
    var rows=table.getElementsByTagName("tr");   
    for(var i=0;i<rows.length;i++)
    {
        ck=rows[i].id; 
        if(x==ck)
        alert("Row clcincked:"+ck); 

    }
}

what exactly you want?
if you want to simply display the clicked button value in another table,
then assign the

function buttonPress(str,x)
{
	var table = document.getElementById('test');   
	var rows=table.getElementsByTagName("tr");   
	for(var i=0;i<rows.length;i++)
	{
		ck=rows[i].id; 
		if(x==ck)
		//alert("Row clcincked:"+ck); 
                // assign it ck to table
		
	}
}

search for google for assigning into table.
or else post your code here, we will assist you.

you just give id to your table rows then,
in your java script you can know which row is clicked like this:

function buttonPress(str,x)
{
    var table = document.getElementById('test');   
    var rows=table.getElementsByTagName("tr");   
    for(var i=0;i<rows.length;i++)
    {
        ck=rows[i].id; 
        if(x==ck)
        alert("Row clcincked:"+ck); 

    }
}

end quote.
