Output of gcloud list commands not displaying in table form

I'm using the gcloud command in Google Cloud Shell. A tutorial I'm following, as well as the documentation (https://cloud.google.com/sdk/gcloud/reference/compute/zones/list), says that to list all the zones in table form you should use this command:

gcloud compute zones list

When I run it the results are listed not in a table, but like this:

NAME: us-west2-b
REGION: us-west2
STATUS: UP
NEXT_MAINTENANCE:
TURNDOWN_DATE:

NAME: us-west2-c
REGION: us-west2
STATUS: UP
NEXT_MAINTENANCE:
TURNDOWN_DATE:

NAME: us-west3-a
REGION: us-west3
STATUS: UP
NEXT_MAINTENANCE:
TURNDOWN_DATE:

This is a brand new pristine Google Cloud account. Did Google change the default output formatting for the list commands?

gcloud config set accessibility/screen_reader false
