I'm trying to group data in a pivot table.
My pivot table has a column that is a 'day' value and i need to
group it by months.
In Excel i can easily do it by right clicking on a cell with a
day and group it.
I noticed in your reference pages that you have a class that
is called GroupFieldImpl, but i couldn't find out how to set it to the table.
Can someone help me please ?
