I have a fancy master-detail grid.
Master grid shows article's information (id, description), real stock, and in others 24 columns shows monthly inputs and outputs.

How can I show in fancy-grid only the movements of inputs or outputs of a month by clicking the respective column?

Example:

January In – January Out – February In – February Out
10 7 45 30

"10" would show the IN movements of January
"30" would show the OUT movements of February
