Change width of a column in a table in Notes.app on a Mac
I discovered the nifty table feature (rows and columns) available in Notes.app on macOS Mojave.
How does one stretch or narrow the width of a column?
The rows and columns of Apple Notes's tables should automatically adjust to fit content. There is no control to explicitly set a width or height, apart from adding whitespace to increase text length (not recommended).
Like @Benj mentioned you can add spaces to one of the cells and the Notes app will adjust the size of the column accordingly. It's not ideal but sometimes it helps when you don't want the text to wrap around
Adding blank spaces to the top row is the fix I found for printing out a few tables I wanted without wrap-around text. It was mentioned that this isn't an ideal solution but it worked fine for adjusting column sizes in my use.
Adding a newline character within the cell helped to keep the cell content somewhat aligned to a fixed size that I wanted.
I used OptionReturn on Mac and ShiftEnter on Windows.
