The benefit of working with tables is their tabular structure. This allows you to visually compare data among rows. However, in editor mode, the table rows are not visually aligned, erasing a huge benefit of tables. Manually spacing out tables is untenable as a table grows in size.
I just created an account to help bumping this point. This would be huge IMO. I use a lot of tables and being able to just press two buttons and have them “prettified” would be a fantastic feature. Even iA Writer has that!
