Vizlib Pivot hiding columns

[Der_Unbekante_234]

Hello everyone,

currently I'm working on a Dashboard via Qlik Sense and created a vizlib pivot table. 

What I try or want to do:

1.) I want to display only the three relevant certification types (DIN EN 15085, AS9100C, IRIS) and not all 100 certificates. I want to hide the other certifications. 

I tried to sort the relevant certificates, so that I can see them at the first row (seems to work not right):

=match(CERTIFICATION_NAME, 'IRIS', 'DIN EN 15085', 'AS9100C', 0)

2.) I want to make the expiry date like the traffic light systems with green (Expiry date is still valid), orange (expires soon), red (is already expired) color --> See the screenshot. Where the '-' is standing is the date. 

I would be happy to receive any help. I already searched on youtube, google and here in the forum for some solutions without any success.

Thanks in advance and Best wishes

for the first point may be try below

pick(match(CERTIFICATION_NAME, 'IRIS', 'DIN EN 15085', 'AS9100C'),'IRIS', 'DIN EN 15085', 'AS9100C')

second point I can't understood clearly
