salut GGtry
vraiment tu es super.
je te remerci beaucoup.
mais d'autre inquietude qui ceci
si je veux suprimer une ligne (row), comment ca se fait?
merci beaucoup une fois encore

Bonjour,

Cela dépend de ce que tu veux supprimer exactement.
Ici, un exemple, où tu rajoutes un boutton "effacer" sur chacune de tes lignes en récupérant dans l'appel à une fonction javascript l'id de ton tr :  newRow +="<td><input type=button value=Effacer onclick=effacer2('hRow"+rowCount+"')></td>"
La fonction javascript pourrait être simplement :
 function effacer2(taRow) {
            var list = document.getElementById(taRow).parentNode;
            list.innerHTML = ""
        }
