如何在Excel中隱藏行？

Question

我有以下代碼可以隱藏某些行：

private static readonly Double DISPLAYED_HIDDEN_CUTOFF_VAL = 0.01;
private bool _hide;
. . .
_hide = racda.TotalItemPercentageOfItem < DISPLAYED_HIDDEN_CUTOFF_VAL;
if (_hide) 
{
    var hiddenRange = _xlSheet.Range[_xlSheet.Cells[_curDescriptionTopRow, ITEMDESC_COL], _xlSheet.Cells[_curDescriptionTopRow, TOTALS_COL]];
    hiddenRange.EntireRow.Hidden = true;
}

該代碼應在適當的時候到達，但沒有效果：這些行仍然可見。 我希望它們出現在電子表格中，但默認情況下不可見。

我該怎么做？

更新

這也行不通：

hiddenRange.Rows.Hidden = true;

...事實上，這導致該應用程序崩潰：

hiddenRange.Hidden = true;

甚至這些試圖實現目標的偷偷摸摸的方式也無濟於事：

//hiddenRange.RowHeight = 0; <= did nothing
hiddenRange.Rows.RowHeight = 0; // <= also does nothing

更新3

是的，您說得對，MacroMarc（在下面回復您的評論）； 該測試代碼可以正常工作：

var testRange = _xlSheet.Range[_xlSheet.Cells[2, 1], _xlSheet.Cells[2, 4]];
testRange.EntireRow.Hidden = true;

...所以關於我的代碼，我的大腦有些混亂。 也許這是一個時機問題； 我將用細齒梳再次檢查它。

Dicho組合代碼為：

    foreach (RawAndCalcdDataAmalgamated racda in 
_rawAndCalcdDataAmalgamatedList)
    {
        _hide = racda.TotalItemPercentageOfItem < 
DISPLAYED_HIDDEN_CUTOFF_VAL;
        AddDescription(racda.ItemDescription);
        AddDataLabels();

        AddMonthData(racda.PackagesMonth1, racda.PurchasesMonth1,
racda.AvgPriceMonth1,
            racda.PercentOfTotalMonth1, MONTH1_COL);
        AddMonthData(racda.PackagesMonth2, racda.PurchasesMonth2, 
racda.AvgPriceMonth2,
            racda.PercentOfTotalMonth2, MONTH2_COL);
        AddMonthData(racda.PackagesMonth3, racda.PurchasesMonth3, 
racda.AvgPriceMonth3,
            racda.PercentOfTotalMonth3, MONTH3_COL);
        AddMonthData(racda.PackagesMonth4, racda.PurchasesMonth4, 
racda.AvgPriceMonth4,
            racda.PercentOfTotalMonth4, MONTH4_COL);
        AddMonthData(racda.PackagesMonth5, racda.PurchasesMonth5, 
racda.AvgPriceMonth5,
            racda.PercentOfTotalMonth5, MONTH5_COL);
        AddMonthData(racda.PackagesMonth6, racda.PurchasesMonth6, 
racda.AvgPriceMonth6,
            racda.PercentOfTotalMonth6, MONTH6_COL);
        AddMonthData(racda.PackagesMonth7, racda.PurchasesMonth7, 
racda.AvgPriceMonth7,
            racda.PercentOfTotalMonth7, MONTH7_COL);
        AddMonthData(racda.PackagesMonth8, racda.PurchasesMonth8, 
racda.AvgPriceMonth8,
            racda.PercentOfTotalMonth8, MONTH8_COL);
        AddMonthData(racda.PackagesMonth9, racda.PurchasesMonth9, 
racda.AvgPriceMonth9,
            racda.PercentOfTotalMonth9, MONTH9_COL);
        AddMonthData(racda.PackagesMonth10, racda.PurchasesMonth10, 
racda.AvgPriceMonth10,
            racda.PercentOfTotalMonth10, MONTH10_COL);
        AddMonthData(racda.PackagesMonth11, racda.PurchasesMonth11, 
racda.AvgPriceMonth11,
            racda.PercentOfTotalMonth11, MONTH11_COL);
        AddMonthData(racda.PackagesMonth12, racda.PurchasesMonth12, 
racda.AvgPriceMonth12,
            racda.PercentOfTotalMonth12, MONTH12_COL);
        AddMonthData(racda.PackagesMonth13, racda.PurchasesMonth13, 
racda.AvgPriceMonth13,
            racda.PercentOfTotalMonth13, MONTH13_COL);

        AddTotalsColData(racda.TotalItemPackages, 
racda.TotalItemPurchases, racda.TotalItemAvgPrice,
            racda.TotalItemPercentageOfItem);

        if (_hide)
        {
            var hiddenRange = 
_xlSheet.Range[_xlSheet.Cells[_curDescriptionTopRow, ITEMDESC_COL], 
_xlSheet.Cells[_curDescriptionTopRow, TOTALS_COL]];
            hiddenRange.EntireRow.Hidden = true;
        }
        _lastRowAdded = _curDescriptionTopRow + 3;
        AddBottomBorder(_lastRowAdded);
        _curDescriptionTopRow = _curDescriptionTopRow + 4;
    }

...或者，去除了多余的細節：

        foreach (RawAndCalcdDataAmalgamated racda in 
_rawAndCalcdDataAmalgamatedList)
        {
            _hide = racda.TotalItemPercentageOfItem < DISPLAYED_HIDDEN_CUTOFF_VAL;

            AddMonthData(racda.PackagesMonth1, racda.PurchasesMonth1, racda.AvgPriceMonth1,
                racda.PercentOfTotalMonth1, MONTH1_COL);
            . . .

            if (_hide)
            {
                var hiddenRange = _xlSheet.Range[_xlSheet.Cells[_curDescriptionTopRow, ITEMDESC_COL], _xlSheet.Cells[_curDescriptionTopRow, TOTALS_COL]];
                hiddenRange.EntireRow.Hidden = true;
            }
            _lastRowAdded = _curDescriptionTopRow + 3;
            _curDescriptionTopRow = _curDescriptionTopRow + 4;
        }

更新4

現在正在工作； 我不得不將行范圍從單個更改為多個：

if (_hide)
{
    var hiddenRange = _xlSheet.Range[_xlSheet.Cells[_curDescriptionTopRow, ITEMDESC_COL], _xlSheet.Cells[_lastRowAdded, TOTALS_COL]];
    hiddenRange.EntireRow.Hidden = true;
}

...也許它按以前的方式工作，我只是沒有注意到，因為我編碼的內容（僅在閾值以下的四分之一隱藏了一行）不是我想要的（隱藏閾值的四行全部） ）。

現在的問題是，它們（某些行）是隱藏的，但是我看不到用戶如何使這些行可見（這是傳統的手工電子表格的工作方式）。

我在這里找到了如何做（手動取消隱藏）的方法。 我真的不需要自己做，我只需要知道用戶可以做到。

如果您不介意使用其他庫，則在使用Excel並免費使用時，ClosedXML很棒。

https://closedxml.codeplex.com/

這是一個如何在工作表中隱藏行的示例：

 var wb = new XLWorkbook();
 var ws = wb.Worksheets.Add("Hide Unhide");
 ws.Columns(1, 3).Hide();
 ws.Rows(1, 3).Hide();
 ws.Column(2).Unhide();
 ws.Row(2).Unhide();
 wb.SaveAs("HideUnhide.xlsx");

來源： https : //closedxml.codeplex.com/wikipage?title=Hide%20Unhide%20Row%28s%29%2fColumn%28s%29&referringTitle=Documentation

強烈建議您使用它，它為多個函數提供了許多有用且不錯的命名約定。 希望對您有所幫助！

這是我首先以特定的方式使其工作的方式：

private static readonly Double DISPLAYED_HIDDEN_CUTOFF_VAL = 0.01;
private bool _hide;
private Worksheet _xlSheet;
. . .
_hide = racda.TotalItemPercentageOfItem < DISPLAYED_HIDDEN_CUTOFF_VAL;
. . .
if (_hide)
{
    var hiddenRange = _xlSheet.Range[_xlSheet.Cells[_curDescriptionTopRow, ITEMDESC_COL], _xlSheet.Cells[_lastRowAdded, TOTALS_COL]];
    hiddenRange.EntireRow.Hidden = true;
}

...現在以更一般/抽象的方式：

if ([some condition where you want rows to be hidden])
{
    var hiddenRange = yourWorksheet.Range[yourWorksheet.Cells[firstRowToHide, firstColToHide], yourWorksheet.Cells[lastRowToHide, lastColToHide]];
    hiddenRange.EntireRow.Hidden = true;
}
