I think you mean you want to find the largest. 
my $largest = @table ? $table[0][0] : undef;
for my $y (0..$#table) {
   my $row = $table[$y];
   for my $x (0..$#$row) {
      $largest = $row->[$x] if $largest < $row->[$x];
   }
}

Same idea for more dimensions. If the number of dimensions is variable, you can use Algorithm::Loops's NestedLoop.

Update: Fixed bug in code.
