You don't need (and shouldn't use) fitsPage to set the tabe width. Use table.setTotalWidth(document.right() - document.left()) and place the table at position document.left().
Table width is working right.
The problem is with table height value. I use tableheight to set document top margin. This is done to avoid header content overlapping with document content.
Sometimes the execution sequence
writer.fitspage(oTable); oTable.getTotalHeight() gives one value
and
document.add(oTable); oTable.getTotalHeight() gives another value
The value that appears to be right is the value obtained after document.add(). I previously posted an example where the two values are different.
If you had any suggestion on how to obtain table height I'd really appreciate it.
Thanks, Rolando.
