Pivot table - update format result

The result of pivot table is not optimised. It would be great if :

- when there is no data in the value, let a blanck rather than put a 0.

- for subtotals, put the line in bold or in another color to separate the line from the detail

- modify the display to create block with +/- for each line value which have line below, like in Excel, to be able to hide detail (see below)

I agree, the display could made a lot cleaner if they added the ability to collapse and expand the rows with the +/- buttons, also I wish there was a way to edit the width of columns so the headers don’t get cut off
