When resizing grid columns so the last column does not reach the right border of the grid (sum of columns width < current grid width), loading stored state (or changing column width property in any way) does not restore the columns width proportionaly to use the full width of the grid.
Note: in this case, the default columns width sum and stored state columns width sum are always inferior to the grid width in order to use proportionality and adapt to every screen size.
In our implementation, we made a "Reset columns view" (working exactly as the loading store data), but if the user play arround with the columns as described above), the reset is broken.
Using the persisting state exemple available in the doc: https://stackblitz.com/edit/angular-3jdmzy?file=app%2Fapp.component.ts
- Click "Save current state"
- Resize grid columns so the last column does not reach the right border of the grid
- Click "Load saved state", the columns are resized proportionaly of the saved state but on the base of previous columns width sum instead of the full grid width.
