Fix bugs and tidy cell plugin .table()

I'm using `.table()` for a project and have found some bugs. For this function, I've:
- Updated the params options
- Fixed how default values are set -- before `printHeaders` was always being set to true
- Removed `autoStretch` -- there was no implementation for that param
- Fixed the code to properly check what values were set for the config params (including if a default value was used)
- Fixed a bug in the autoSize functionality in the `for` loop variable names
