Hello,

I have been looking into your requirement and my suggestion is to retemplate the igxCellEditor by adding and input and set its maxLength property to the desired value.

I created a small sample in order to demonstrate how such behavior could be achieved by setting the maXLength property of the "Country" column to 12:

<igx-column field="Country" [resizable]="true" [editable]="true">
           <ng-template igxCellEditor let-cell="cell">          
                <igx-input-group>
                    <input igxInput name="country" type="text" maxLength="12"
                    [(ngModel)]="cell.value"/>
                </igx-input-group>             
           
        </ng-template>
        </igx-column>

Here could be found my sample for your reference. Please test it on your side and let me know if I may be of any further assistance.
