When there are a lot of rows in a table, especially when they’re grouped and color-coded with conditional formatting, it can be difficult to see the gridlines and distinguish between rows. A nice accessibility feature would be the ability to make the gridlines thicker between rows AND to add thick gridlines between grouped sections. Could easily be grouped in the settings similar to text size options.
Ditto this request. The ability to change the color of the gridlines would help as well.
