I rememeber sometimes doing something like this when
using CGI.pm and DBI.pm
push(@rows,td({-colspan=>'6',-bgcolor=>'#FFFFFF'},[$th]));
#blank row
$th = ' ';
push(@rows,td({-colspan=>'6',-bgcolor=>'#FFFFFF'},[$th]));
push(@rows,td({-bgcolor=>'#FFCC99'},['',b('Verwijderen:'),b('Naam:'),b('Voornaam:'),b('Vertegenwoordiger:*'),b('Bekijk
CV:')]));
while (@data = $cursor->fetchrow) {
$count++;
if ($count % 2 == 0){
$bgcolor = "#FFCC99";
}else{
$bgcolor = "#FFFFFF";
}
etc..
and then i the end i printed the table
$innertable = table({-border=>'0',-width=>'100%',
-cellspacing=>'1', -cellpadding=>'2',
-bgcolor=>'#FFFFFF'},Tr(\@rows));
I always founded this a very nice feature of CGI.pm.
The only thing i never found out is how you could
manipulate tables in this same kind of way ?
Thanks,
