You can edit the style of your tables by going to Edit Design > Table Styles
Select either the header row, body row or footer row to begin editing properties.
With an element selected, you can change the background color, border size and color. (The text styles are defined under Typography).
With the body row element selected you have the option to turn on alternate rows to give you the zebra striping (every other row is different).
Once it's check on, you will be able to define the background color, border size and border color of both the odd and even rows.
