Single line listing with every other row color


We are making a test run and wonder is there a possibility to have a single line listing (for a lot of info on a page) plus every other row color - like 1 row grey, second black and so on.

And also headers for grouping?

We are releasing a table block soon. Although first without grouping

Any progress regarding grouping? Would love to have this feature!
