Supernotes supports Markdown tables – which are super simple and easy for basic data comparison.

Start by creating a header row naming each column you'd like and separate them with a vertical line,  | . After this header row, on a new line replicate the number of columns you'd like but this time use three dashes, --- , this tells Markdown to treat this as a table. Then on another new line you can follow the same method but just input the data for each row, like so:

And here is it working in Supernotes:

When you finish the card, the table will be rendered beautifully.
