如何在Excel中隐藏行？

问题描述 投票：0回答：2

我有这个代码隐藏某些行：

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;
}

应该到达代码，但它没有效果：这些行仍然可见。我希望它们在电子表格中，但默认情况下不可见。

我怎么能做到这一点？

UPDATE

这也行不通：

hiddenRange.Rows.Hidden = true;

......事实上，这导致应用程序崩溃：

hiddenRange.Hidden = true;

更新2

即使是这些相当偷偷摸摸的尝试完成它的方法也没有做任何事情：

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

更新3

是的，你是对的，MacroMarc（回复你下面的评论）;这个测试代码确实有效：

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

......所以我的大脑中有一些与我的代码有关的东西。也许这是一个时间问题;我会用细齿梳子重复它。

Dicho discombobulatory代码是：

    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，删除了无关的细节：

        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

它现在正在运作;我不得不将行范围从单个行更改为多个：

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

...也许它之前的编码工作，我只是没有注意到它，因为我编码的内容（只隐藏了低于阈值的每四个中的一行）不是我想要的（将所有四行隐藏在阈值之下） ）。

现在的问题是它们（某些行）是隐藏的，但我没有看到用户如何使这些行可见（这是传统手工制作的电子表格的工作方式）。

我发现了如何做到这一点（手动取消隐藏）here。我自己并不需要这样做，我只需要知道用户可以做到这一点。

如果您不介意使用其他库，那么在使用Excel并免费使用时，ClosedXML非常棒。

https://closedxml.codeplex.com/

以下是如何隐藏工作表中的行的示例：

 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");

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

强烈推荐它，它为几个函数提供了许多有用且好的命名约定。希望有所帮助！

这是我开始工作的方式，首先是以特定的方式：

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;
}

......现在采用更一般/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;
}
