I guess I'm not understanding this. You have a table with 100% cell and the flash is in that. So yeah there's whitespace. Set the size of the cell to the same as the flash. This is pretty basic layout stuff. If you want that INSIDE another table cell that's fine that one can be 100% to keep it centered like you have it now.

And even if you can't do that set the background color of the page and then set the tables bg color the same, visibly it will be the same.
