Is't possible to hide header title dimensions and se only the values?

Hi Biagio!
Thank you for posting your question. 

To customize the appearance of the grid, you can use an options object. It’s possible to hide only the hierarchy captions but the names of the hierarchy members cannot be hidden. 
We’ve prepared a demo for you that shows how to use options to hide the hierarchy captions and grid’s headers. 
 

To find more details, please refer to the documentation. 
Hope this will be useful for your case.

Thanks. I’m able to remove headers and with css code, I hidden the menu on the right.
Ho to move columns to left for not wasting space?

Hello Biagio,
Thank you for your feedback.

It is not possible to remove the member column of pivot table.
The possible options is to resize the column and make it narrower.
Also, please consider switching from pivot table view to flat form.
In such a case, you can display only columns with values and nothing more.
