Pivot table design and column width

[JMoreno]

Hi, 

Is there a way to to customise a pivot table? Mainly, I'm looking for how to reduce the column width.  I have the following example in a pivot table with 12-18 columns (city names), and it is not possible to see them all at once, because it keeps this column width despite all the empty space. 

I haven't been able to find a solution or an extension that could be useful (apart from the VizLib ones which we cannot pay). 
Are you aware of any solution? 

Is this something coming for new releases? 

Thanks! Any help would be very appreciated.
