Hello,

been trying to come up with a way, while going through a loop to 
alternate a table cell color <td></td>....


See if this gets you thinking along the right lines:

my $odd = 1;
while (<>) {    # some kind of loop...
    if ($odd) {
        # do something
        $odd = 0;
    }
    else {
        # do something else
        $odd = 1;
    }
}
or

my $alt;
while (<>) {    # some kind of loop...
    if ($alt = !$alt) {
        # do something
    }
    else {
        # do something else
    }
}
