When using the pivot table I open the configuration popup and there's a list in the left (where you drag stuff from) and a 2x2 table to the right with "rows, columns, values, filters" areas (where you drop the dragged stuff to).
I'd like the droppable area to be 4 columns instead of a 2x2 grid. Is it possible to achieve this with ease? (consider I have set bigger custom width for my popup, so there's room for 4 columns)
Besides my specific question, is there any full complete documentation for customizing this configuration popup? Official documentation only has a couple useful examples(like setting width and height, adding a search widget, or changing the captions), but navigating through the forum I saw there are much more options to play with and I'd like to see and study a complete list of them.
Thank you very much!
