通過對數據進行分組來減少行數

Question

我有一組電子表格，它們定義了一組業務規則。這些業務規則然後由我們的系統處理。

創建電子表格的用戶做得太天真了，我發現通過將行間數據分解 - 從而減少規則數量 - 極大地提高了系統的性能。

其中的「天真」結構化的電子表格可能是這樣的：

+-----------+------------+------------+------------+------------+--------+ 
| Rule Name | Criteron 1 | Criteron 2 | Criteron 3 | Criteron 4 | Accept | 
+-----------+------------+------------+------------+------------+--------+ 
| Rule 1 |  A  |  B  |  C  |   | Yes | 
| Rule 2 |  A  |  C  |  C  |   | Yes | 
| Rule 3 |  A  |  D  |  C  |   | Yes | 
| Rule 4 |  A  |  E  |  C  |   | Yes | 
| Rule 5 |  A  |  F  |  C  |   | Yes | 
| Rule 6 |  A  |  B  |  D  |   | Yes | 
| Rule 7 |  A  |  C  |  D  |   | Yes | 
| Rule 8 |  A  |  D  |  D  |   | Yes | 
| Rule 9 |  A  |  E  |  D  |   | Yes | 
| Rule 10 |  A  |  F  |  D  |   | Yes | 
| Rule 11 |  A  |  B  |  E  |   | Yes | 
| Rule 12 |  A  |  C  |  E  |   | Yes | 
| Rule 13 |  A  |  D  |  E  |   | Yes | 
| Rule 14 |  A  |  E  |  E  |   | Yes | 
| Rule 15 |  A  |  F  |  E  |   | Yes | 
| Rule 16 |   |   |   |  G  | Yes | 
| Rule 17 |   |   |   |  H  | Yes | 
| Rule 18 |   |   |   |  I  | Yes | 
| Rule 19 |   |   |   |  J  | Yes | 
| Rule 20 |   |   |   |  K  | Yes | 
| Rule 21 |   |   |   |  L  | Yes | 
| Rule 22 |   |   |   |  M  | Yes | 
| Rule 23 |   |   |   |  N  | No | 
| Rule 24 |   |   |   |  O  | No | 
| Rule 25 |   |   |   |  P  | No | 
| Rule 26 |   |   |   |  Q  | No | 
| Rule 27 |   |   |   |  R  | No | 
| Rule 28 |   |   |   |  S  | No | 
| Rule 29 |  A  |  J  |  F  |   | No | 
| Rule 30 |  A  |  K  |  F  |   | No | 
+-----------+------------+------------+------------+------------+--------+ 

作爲一個例子，第1條將被評估爲：

IF (Criterion 1 == A) AND (Criterion 2 == B) AND (Criterion 3 == C) THEN Accept 

必須思考和假設我們可以在我們的列中使用OR條件，上面的可以簡化爲：

+-----------+------------+------------+------------+-------------+--------+ 
| Rule Name | Criteron 1 | Criteron 2 | Criteron 3 | Criteron 4 | Accept | 
+-----------+------------+------------+------------+-------------+--------+ 
| Rule 1 |  A  | B,C,D,E,F | C,D,E |    | Yes | 
| Rule 2 |   |   |   |G,H,I,J,K,L,M| Yes | 
| Rule 3 |   |   |   |N,O,P,Q,R,S | No | 
| Rule 4 |  A  |  J,K |  F  |    | No | 
+-----------+------------+------------+------------+-------------+--------+ 

規則1現在是評估如下：

IF (Criterion 1 == A) AND 
    (Criterion 2 == B OR Criterion 2 == C OR...) AND 
    (Criterion 3 == C OR Criterion 3 == D OR...) THEN Accept 

現在，我已經做了這個手動。我想知道的是：Excel是否具有內置功能來爲我進行這種分組。如果沒有，任何人都可以指向我的算法的方向，這將有助於我有效地實現這一點？

這看起來像一個情況下，你可以查詢使用ADO和OLE DB到ADO記錄集使用GROUP表由SQL查詢HAVING，然後轉儲（分組）的結果爲使用CopyFromRecordset

你的新工作表

另外，也許是一個數據透視表？
