Anomalia grandezza automatica celle tabella

Salve raga, ho un problema nella grandezza automatica delle celle di una tabella solo su alcune righe: Ecco il codice

//ciclo su vigneti 
for($i=1; $i<=3; $i++){ ?>

 <form action="nota-consulenza.php" method="GET">

<?php } //chiusura 1° ciclo for ?>

Ecco il link della pagina: "app.danielebarisano.it/vigneto/medicina.php" Come potete notare, solo sulla 1°riga di ognuna delle 3 tabelle si imposta la grandezza cella in automatico in base al contenuto. Nelle altre no.

Sapete dirmi il perchè trattandosi dello stesso codice?
