hi,
by turning table or cell into a layer. See this CSS-definitions:
table.innen{position:absolute;top:200px;left:200px;}
and this table:
<TABLE Class="innen" BORDER=1 CELLSPACING="0" CELLPADDING="0"><TR><TD WIDTH="50" HEIGHT="50" NOWRAP>Your Text</TD></TR></TABLE>
Now the table is positioned 200px far from the left and top edge.
but...test it, might be buggy in some situations. Of course only working with generation 4.x ;-)
all the best Joachim
