Table output cannot handle non-toplevel arrays

There appears to be an issue where the -o table type cannot handle non-toplevel arrays. This is visible by running through some steps from an upcoming conceptual tutorial document:

az group create --name TutorialResources --location eastus

az vm create --resource-group TutorialResources \
          --name TutorialVM1 \
          --image UbuntuLTS \
          --generate-ssh-keys \
          --verbose

NIC_ID=$(az vm show -n TutorialVM1 -g TutorialResources \
          --query 'networkProfile.networkInterfaces[].id' \
          -o tsv)

        az network nic show --ids $NIC_ID \
          -g TutorialResources \
          --query '{IP:ipConfigurations[].publicIpAddress.id, Subnet:ipConfigurations[].subnet.id}' \
          -o json

{
  "IP": [
    "/subscriptions/.../resourceGroups/TutorialResources/providers/Microsoft.Network/publicIPAddresses/TutorialVM1PublicIP"
  ],
  "Subnet": [
    "/subscriptions/.../resourceGroups/TutorialResources/providers/Microsoft.Network/virtualNetworks/TutorialVM1VNET/subnets/TutorialVM1Subnet"
  ]
}

However, if we change the last command to use -o table instead, no output is printed.

        az network nic show --ids $NIC_ID \
          -g TutorialResources \
          --query '{IP:ipConfigurations[].publicIpAddress.id, Subnet:ipConfigurations[].subnet.id}' \
          -o table

Environment summary

Ubuntu 16 LTS (on WSL) zsh Installed via package az --version: 2.0.25

@gsacavdm That’s a separate issue. There are a few keys we skip currently automatically and id is one of them. This is due to id appearing in almost every command result and them being very long so it’s atypical that you’d want to see it in the default table output of commands.

Change the key name and it will appear. https://github.com/Microsoft/knack/blob/master/knack/output.py#L152

If this is a real issue to you, please open a separate issue. 😃

While we understand the scenario here, currently table requires some specific format to operate and moving it to be more free-form has unintended side-effects and additionally does not promote consistency.
