Get data from hidden columns

[BartoszKosmider]

Hey,
Is there any posibility to get data from hidden columns? I would like to use formatter to display in one column values from others. I would like to leave option to hide columns unremain.
getData() returns only data from columns that are visible and I don't see any other method to do that.
Thanks in advance.

EDIT: grid.getData().getItems()

Perhaps I don't understand your question but you already have all the data since you are the person who is providing that said data to the Angular-Slickgrid [dataset]

<angular-slickgrid gridId="grid4"
      [columnDefinitions]="columnDefinitions"
      [gridOptions]="gridOptions"
      [dataset]="dataset"
</angular-slickgrid>

and please ask such questions on Stack Overflow which is a better platform for Q&A
