Description & motivation

The advanced cloud usage section for the compare-column-values was incorrect, and needed more code / explanation for it to work properly.

Do you think we should instead ship a print_results_cloud() macro that takes audit_results as input? so it would basically be:

Core

{% set audit_results = run_query(audit_query) %}

{% if execute %}
{% do audit_results.print_table() %}
{% endif %}

Cloud

{% set audit_results = run_query(audit_query) %}

{% if execute %}
{% audit_helper.print_results_cloud(audit_results) %}
{% endif %}

This feels nicer than making people create the macro themselves, wdyt?

@joellabes YES!!! love. that would be epic.

Can we merge this working option in the meantime?
