How to select a record by clicking one cell in a grid ExtJS 6

I have a grid and i want to select the whole record by clicking one specific cell. The problem is i cant use the checkboxmodel seltype, cause i want to show a custom icon on every cell. So is there any way to make it possible?

I solved the problem with the beforecellclick event. Now it looks like this:

beforecellclick:function(grid,record,index){
                        if(index != 0){
                            return false
                        }
               }

and I have an action column on colIndex 0:

xtype: 'actioncolumn',
        tooltip:'löschen',
        width: 30,
        icon: '../../../../../../resources/images/16/delete_2.png',
        handler:function(grid, rowIndex, colIndex){
            var record = grid.getStore().getAt(rowIndex);
            if( grid.getSelectionModel().isSelected(record) == false){
                grid.getSelectionModel().select(record, true)
            }else{
                grid.getSelectionModel().deselect(record)
            }      
        }
