Context

I try to catch the available request/limits resource in my cluster with a script to determine if I have enough resource to deploy new pod in my cluster. I want catch this information from a yaml or json output to easily manipulate the output with a jq or yq tool.

Actual results

The option -a is ignored when the output is not table
