Table layout breaks when a value is multiline

[gairadzi]

If the value of one the columns includes a newline character (and the string before it is smaller than the column's max width) the table layout will break.

This can be reproduced by changing the value in line 28 of examples/simplest/main.go to Electric\nhello

This is because the rune width of the first line is smaller than the max width, I believe the expected behavior should be to only show the first line appended by the dots (to indicate it includes further data).

Initially addressed by #52 (linking here for tracking) but still missing one issue.

Turns out this still breaks in an edge case:

If the first line is exactly the max length, adding the ... character at the end makes it too long.

Latest PR should fix this

Released v0.8.4, let me know if this looks good to you and then feel free to close the issue. Thanks again for the contribution!
