Review Comment:
I tried that as well, however since we're explicitly checking for null
values, the expected value would be something like
```
let expected = vec![
"+------------+",
"| string_col |",
"+------------+",
"| |",
"+------------+",
];
```
... making it hard to differentiate between an empty string and null, so I
opted to explicitly test via `Array#is_null`
