解决方案：

Ext.override(Ext.grid.plugin.CellEditing, {startEdit: function(record, columnHeader) {        var me = this,            value = record.get(columnHeader.dataIndex),            context = me.getEditingContext(record, columnHeader),            ed;        record = context.record;        columnHeader = context.column;                        me.completeEdit();        context.originalValue = context.value = value;        if (me.beforeEdit(context) === false || me.fireEvent('beforeedit', context) === false || context.cancel) {            return false;        }                        if (columnHeader && (!columnHeader.getEditor || !columnHeader.getEditor(record))) {            return false;        }                ed = me.getEditor(record, columnHeader);        if (ed) {            me.context = context;            me.setActiveEditor(ed);            me.setActiveRecord(record);            me.setActiveColumn(columnHeader);                        me.editTask.delay(15, ed.startEdit, ed, [me.getCell(record, columnHeader), value]);        } else {                                                            me.grid.getView().getEl(columnHeader).focus((Ext.isWebKit || Ext.isIE) ? 10 : false);        }                return true;    }});
