Borderless Demo in Readme Possibly Erroneous

I copied and pasted the borderless demo from the README verbatim and it's printing empty lines between rows, which seems to run contrary to the expected output according to that section in the README. Here's my output:

```bash
→ node table-test.js

0A 0B 0C

1A 1B 1C

2A 2B 2C
```

Does the README and the section on borderless tables need updating?

Start by reading the borderless-table section in the README and running the referenced table-test.js demo with node. Compare the observed blank lines with the README's expected output, then update the relevant README text or example so the documented behavior and demo agree.
