How to format output of gcloud command, Debian - google-cloud-platform

Question

I'm currently working through some GCP training courses via https://www.cloudskillsboost.google/ and seeing some differences in my output versus the documentation. Not sure if this is down to the software version, account settings or what?
Example given is for a list of firewall rules:
gcloud compute firewall-rules list
and the example output is
NAME NETWORK DIRECTION PRIORITY ALLOW DENY DISABLED
default-allow-icmp default INGRESS 65534 icmp False
default-allow-internal default INGRESS 65534 tcp:0-65535,udp:0-65535,icmp False
default-allow-rdp default INGRESS 65534 tcp:3389 False
default-allow-ssh default INGRESS 65534 tcp:22 False
dev-net-allow-ssh dev-network INGRESS 1000 tcp:22 False
serverless-to-vpc-connector dev-network INGRESS 1000 icmp,udp:665-666,tcp:667 False
vpc-connector-egress dev-network INGRESS 1000 icmp,udp,tcp False
vpc-connector-health-check dev-network INGRESS 1000 tcp:667 False
vpc-connector-to-serverless dev-network EGRESS 1000 icmp,udp:665-666,tcp:667 False
One rule per line with multiple fields horizontally. However, when I run this command in the Cloud Shell I get the following:
NAME: default-allow-icmp
NETWORK: default
DIRECTION: INGRESS
PRIORITY: 65534
ALLOW: icmp
DENY:
DISABLED: False
NAME: default-allow-internal
NETWORK: default
DIRECTION: INGRESS
PRIORITY: 65534
ALLOW: tcp:0-65535,udp:0-65535,icmp
DENY:
DISABLED: False
NAME: default-allow-rdp
NETWORK: default
DIRECTION: INGRESS
PRIORITY: 65534
ALLOW: tcp:3389
DENY:
DISABLED: False
NAME: default-allow-ssh
NETWORK: default
DIRECTION: INGRESS
PRIORITY: 65534
ALLOW: tcp:22
DENY:
DISABLED: False
NAME: fw-allow-health-check
NETWORK: default
DIRECTION: INGRESS
PRIORITY: 1000
ALLOW: tcp:80
DENY:
DISABLED: False
NAME: www-firewall-network-lb
NETWORK: default
DIRECTION: INGRESS
PRIORITY: 1000
ALLOW: tcp:80
DENY:
DISABLED: False
It's the same data but the layout is different. (Appreciate that output is not identical, but I'm ot concerned abiout that. Differences between sample and live data is ok here I think)
Now, you can change the output format with the format option, but I can't recreate this tab separated table.
Is this just down to the documentation reformatting the output? Is it down to the software version or a setting I've missed? Can the format option do this and I've just not figured it out?
Any pointers much appreciated, as it's frustrating me.

Answer 1

Sharing you the best practices document [1], which explains the ways to format with example scripts.
You can check the possible outputs of --format in the [2] and also a similar thread [SO link] explains the ways to generate excel format output.
