Other than not printing the tab character that you show at the end of the 2nd line of your specified sample output, the following seems to do what you want:
Code:
awk '
$1 ~ /:/ {
	if(t) p()
	t = $1
	mf = NF - 1
	for(i = 3; i <= NF; i++) 
		m[i - 1] = $i
	next
}
function p(	i) {
	printf("%s %4s ", t, m[2])
	for(i = 3; i <= mf; i++)
		printf("%8s%s", m[i], i == mf ? "\n" : " ")
}
{	for(i = 2; i <= mf; i++)
		if(m[i] < $i)
			m[i] = $i
}
END {	p()
}' file

As always, if you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk, /sur/xpg6/bin/awk, or nawk.
