Change selection only on specific column

[EmCy90]

Lets say we have a grid panel with column A and column B. What i want to do is the selection to be changed only when the user selects the part of the row that is under column A. Is this possible ?

It is:

getTargetFromEvent: function(event) {
        var me = this,
            view = me.view;


        var cell = event.getTarget(view.cellSelector);


        if (this.targetCell !== cell) {
            view.fireEvent('cellchange', this.targetCell, cell, event);
            this.targetCell = cell;
        }


        if (cell) {


            var row = view.findItemByChild(cell),
                columnIndex = cell.cellIndex;


            if (row && Ext.isDefined(columnIndex)) {


                return {
                    node: cell,
                    record: view.getRecord(row),
                    fieldName: me.columns[columnIndex].dataIndex
                };
            }
        }
    },
