Using Tables?

I'm trying to wrap my head around openPeripherals but I'm having issues working out how to access the info shown in the table created when using "getTankInfo()" How can I see it?

Just use a for loop to get all the elements in a table

for k,v in pairs(table) do
  print("["..k.."] = "..v)
end

To acess the fields, just use table.key
if the field is a number, use table[key]

Also, you can use variable as table key, for example:

local key = "black"
term.setBackgroundColor(colors[key])

You can think about square brackets in tables as "get value from stuff inside and use it as table key".
