Formatting script output-CodePudding

I created this script which generates the following output:

### NODE 1 ###
IP: 192.168.1.100
MASK: 225.255.255.0
GATEWAY: 192.168.1.1

### NODE 2 ###
IP: 192.168.1.101
MASK: 225.255.255.0
GATEWAY: 192.168.1.1

Is there any way to force the output to look like this instead?

### NODE 1 ###        ### NODE 2 ###
IP: 192.168.1.100     IP: 192.168.1.101
MASK: 225.255.255.0   MASK: 225.255.255.0
GATEWAY: 192.168.1.1  GATEWAY: 192.168.1.1

If you have an unknown number of nodes, the format you proposed is actually pretty bad because you'll run too wide with just several nodes. May I propose the following:

    Node Name   IP            Netmask       Gateway
    Node 1      192.168.0.100 255.255.255.0 192.168.1.1
    Node 2      192.168.0.101 255.255.255.0 192.168.1.1

But if you insist on the column per node format then I'd make use of arrays.

You want the pr command
