如何使用Apache POI

如何禁用使用Apache POI中間總，我用這個apache的POI禁用中間總，我想中間總應禁用如何使用Apache POI

這裏是Excel輸入對於理解

在Excel版本，你可以出示你預期的結果？我使用你的代碼，並創建一個數據透視表，與相同的數據，並且都看起來相同（就像你當前的結果） – XtremeBaumer

謝謝，以前我們正在手動，但現在我們已經自動化這個過程，因爲我發現這個apache poi圖書館，並試圖用它 –

這不回答我的問題 – XtremeBaumer

就我所見，您的主要要求是擺脫小計。這可以使用org.openxmlformats.schemas.spreadsheetml.x2006.main.CTPivotField.setDefaultSubtotal(false)。

這裏也詢問了這個問題Apache POI XSSFPivotTable setDefaultSubtotal。

你的榜樣：

      XSSFPivotTable pivotTable = sheet.createPivotTable(new AreaReference(new CellReference(0,0),new CellReference(4,sheet.getRow(0).getLastCellNum()-1)), new CellReference(0,7)); 

      pivotTable.addRowLabel(0); 

    //set tabular layout instead of tree layout 
    pivotTable.getCTPivotTableDefinition().getPivotFields().getPivotFieldArray(0).setOutline(false); 

    /* 
    Apache poi adds 5 pivot field items of type "default" (<item t="default"/>) here. 
    This is because there are 5 rows (A1:C5) and, because they don't have a look at the data, 
    they are assuming max 5 different values. This is fine because Excel will rebuild its pivot cache while opening. 

    But if we want changing defaults, then this is not fine. Then we must know what items there are. 

    So we need at least as much items, as where different ones in the data, as numbered items: <item x="0"/><item x="1"/> 

    And we must build a cache definition which has shared elements for those items.
