Formatting/Justifying Subforms in Canvas

Formatting/Justifying Subforms in Canvas

Hi! This community has been so helpful! Hoping somebody can also help me with this Canvas design issue -- I don't see any option to customize the column width or justify the text in a Subform within Canvas?

As you'll see attached, I have a "date" column that can be quite narrow and then a text column that should be wider, but the Canvas seems to automatically justify all columns/text to the right? Can I fix this somehow???
