    # 加總平行四邊型範圍內的數字 有沒有什麼簡便的方法,來加總平行四邊型範圍內的數字呢? ![](https://i.imgur.com/ruzH1sK.png) 上圖為改編自真實案例的概念示意圖。 我試了四種方法,覺得沒有一種是足夠優雅的。全數列在下面供大家參考。 也歡迎提供更漂亮的方法。 以下每一個方法都會附上一格公式範例。細節則請參考[完整範例檔](https://l.facebook.com/l.php?u=https%3A%2F%2Fdocs.google.com%2Fspreadsheets%2Fd%2F1cClNHaF3JlAzpqlT1GocvDG7SCGqPSlX%2Fedit%3Fusp%3Dsharing%26ouid%3D104967339353629245893%26rtpof%3Dtrue%26sd%3Dtrue%26fbclid%3DIwAR3ApBD6YScf5Lkk6IS18tt-aVdSjmoDz5LbarK86snowIYJsGGQ9aUihDM&h=AT2B0ZX4JLBB4FEGtaZLptdKNsFhyDSSfWGtGyMXhte-vNfvwMbtedv-0oYLis5mCpswYpWhTWRAxLFxmY6fGcjBJES1M_AVleBoGOuzg-eyQLbG3QvVvVxXA4de8u9rDw&__tn__=R]-R&c[0]=AT1sZgfQDlVIR_BgvPSI6P0qPHpnO9DDVxVWyEf8ZnDSzy-ltFRVU5El0m_W1hsqdUnPcEXzP4d4UlpTB1-k00Hz0_nsiDKbi07qf1qRx2khadDbOj_nDA7isyG0YdhdBgtdfft7oGC-4kd83G16J6Re8r4)。 ## 方法一 使用SUM函數,並且手動慢慢把要加總的範圍填入函數的引數中。 這種方法給人帶來一種勤勞的美感。 而且如果要框選的範圍不大,這樣做確實可以比寫複雜的公式要快得多。 ``` =SUM('raw data'!B2:B13,'raw data'!C2:C12,'raw data'!D2:D11,'raw data'!E2:E10,'raw data'!F2:F9,'raw data'!G2:G8,'raw data'!H2:H7,'raw data'!I2:I6,'raw data'!J2:J5,'raw data'!K2:K4,'raw data'!L2:L3,'raw data'!M2) ``` ## 方法二 類似中學數學的線性規劃,用二元一次方程式的概念把我們要加總的區域表達出來。然後用SUMIFS函數,針對符合條件的儲存格做加總。 因平行四邊型有四個邊,每個邊都可以用一條方程式來表達。每一條方程式就是一個條件,所以每個SUMFIS的公式裡都會用到四個條件。 此方法不需要任何計算輔助區,也不受限於欄/列的名稱格式,純粹以幾何概念對平行四邊型的範圍做加總。 (提醒:此為陣列公式,需按Ctrl + Shift + Enter以完成輸入) ``` {=SUM(range* ((ROW(range)+COLUMN(range))>IFERROR((RIGHT(A$10,4)-2012),-1)*12+15)* ((ROW(range)+COLUMN(range))<=(RIGHT(B$10,4)-2012)*12+15)* (COLUMN(range)>IFERROR((LEFT($A10,4)-2012),-1)*12+13)* (COLUMN(range)<=(LEFT($A11,4)-2012)*12+13))} ``` ## 方法三 另闢一區與原始資料範圍1:1的計算輔助區,在輔助區做判斷,在原始資料區做加總。 ``` =SUMIFS(range, ref,">="&LEFT($A19,4), ref,"<"&LEFT($A19,4)+1, ref,">="&LEFT($A19,4)&"."&RIGHT(B$18,4), ref,"<"&LEFT($A19,4)&"."&RIGHT(B$18,4)+1) ``` 輔助區公式示例: ``` =LEFT(B$1,4)+LEFT(B$1,4)/10000+((RIGHT($A2,2)-1)/12/10000)+((RIGHT(B$1,2)-1)/12/10000) ``` ## 方法四 另闢一區輔助區,在輔助區對原始資料的各欄列做平移,把平行四邊型改換成同面積的矩型再做加總。 ``` =SUM(OFFSET(ref_2!$B$2, (RIGHT(B$26,4)-2012)*12, (LEFT($A27,4)-2012)*12,12,12)) ``` 輔助區公式示例: ``` =IF(ISNUMBER(OFFSET('raw data'!B2,-(COLUMNS($B:B)-1),0)),OFFSET('raw data'!B2,-(COLUMNS($B:B)-1),0),0) ``` ## 範例下載 [完整範例檔](https://l.facebook.com/l.php?u=https%3A%2F%2Fdocs.google.com%2Fspreadsheets%2Fd%2F1cClNHaF3JlAzpqlT1GocvDG7SCGqPSlX%2Fedit%3Fusp%3Dsharing%26ouid%3D104967339353629245893%26rtpof%3Dtrue%26sd%3Dtrue%26fbclid%3DIwAR3ApBD6YScf5Lkk6IS18tt-aVdSjmoDz5LbarK86snowIYJsGGQ9aUihDM&h=AT2B0ZX4JLBB4FEGtaZLptdKNsFhyDSSfWGtGyMXhte-vNfvwMbtedv-0oYLis5mCpswYpWhTWRAxLFxmY6fGcjBJES1M_AVleBoGOuzg-eyQLbG3QvVvVxXA4de8u9rDw&__tn__=R]-R&c[0]=AT1sZgfQDlVIR_BgvPSI6P0qPHpnO9DDVxVWyEf8ZnDSzy-ltFRVU5El0m_W1hsqdUnPcEXzP4d4UlpTB1-k00Hz0_nsiDKbi07qf1qRx2khadDbOj_nDA7isyG0YdhdBgtdfft7oGC-4kd83G16J6Re8r4) ![](https://i.imgur.com/aVeht0H.png) ![](https://i.imgur.com/a63blGK.png)
