Spazio tra tabelle (solo con IE)

[web@web]

ho il foglio diviso in varie tabelle una sopra l'altra.
Con Mozilla e Opera il layout è perfetto, con IE mi fa degli spazi (anche enormi) tra una e l'altra.
Ho provato con

cellspacing
cellpadding
margin
border
....


non so più cosa provare!!!

[web@web]

posto il codice, forse capite meglio

<div align="center">
