How to change the height of one row in a grid of many rows?

I have a grid with few rows. How can I change the height of the third row to 20px and all the other rows should be 10px.

I have attached a image of the design that I am looking for. A syntax example will be very helpful.
Please help

I haven’t tried it, but as far as I know, Grid currently only supports rows that have same height. I haven’t checked if there’s some serious problems with rows of varying heights in Grid, they might work to some degree. In Table they work rather well, with just some minor issues, even though they are not supported.

I’d think you can set the row heights with a RowStyleGenerator.
