默认extjs中editorgrid编辑单元格的时候按回车是将焦点向下移动，按照一般的逻辑应该是向右移动。
其实只要将原先rowSelectionModel中onEditorKey方法override一下即可。
代码如下：
Ext.override(Ext.grid.RowSelectionModel, {
onEditorKey : function(field, e) {
var k = e.getKey(), newCell, g = this.grid, last = g.lastEdit, ed = g.activeEditor, shift = e.shiftKey, ae, last, r, c;
if (k == e.TAB) {
e.stopEvent();
ed.completeEdit();
if (shift) {
newCell = g.walkCells(ed.row, ed.col - 1, -1, this.acceptsNav,
this);
} else {
newCell = g.walkCells(ed.row, ed.col + 1, 1, this.acceptsNav,
this);
}
} else if (k == e.ENTER) {
if (this.moveEditorOnEnter !== false) {
if (shift) {
newCell = g.walkCells(last.row, last.col - 1, -1,
this.acceptsNav, this);
} else {
newCell = g.walkCells(last.row, last.col + 1, 1,
this.acceptsNav, this);
}
}
}
if (newCell) {
r = newCell[0];
c = newCell[1];
this.onEditorSelect(r, last.row);
if (g.isEditor && g.editing) { // *** handle tabbing while
// editorgrid is in edit mode
ae = g.activeEditor;
if (ae && ae.field.triggerBlur) {
// *** if activeEditor is a TriggerField, explicitly call
// its triggerBlur() method
ae.field.triggerBlur();
}
}
g.startEditing(r, c);
}
}
})
