RxDBGrid FooterRows

[melwinek]

I use RxDBGrid with one FooterRow.
I noticed that there is an property FooterRows, which allows for the existence of several lines in the footer.

My grid looks like this:
NAME     | TOTAL PLN | TOTAL EUR
------------------------------------------
NAME1   | 100            |25
NAME2   | 200            |50
------------------------------------------
SUM       | 300            |75

How to perform to grid looks like this:
NAME       | TOTAL PLN
----------------------------
NAME1     | 100
NAME2     | 200
--------------------------
SUM PLN  | 300
SUM EUR  |   75

Has anyone used the FooterRows property with a value >1 ?
