Stripes are for zebras, not tables.
Tables in reports are helpful for presenting information but you need to help your reader to see your message. Formatting your table can help but too much formatting works against you. All you’re doing is adding clutter. In particular, don’t use “zebra striping” (where alternative rows are shaded one darker, one lighter). You may think it makes your tables more organised as well as pretty, but it doesn’t actually help the reader focus on what’s important.
