[英]How can I hide rows in Excel?
I've got this code to hide certain rows: 我有以下代码可以隐藏某些行:
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;
}
The code is reached when it should be, but it has no effect: those rows are still visible. 该代码应在适当的时候到达,但没有效果:这些行仍然可见。 I want them to be on the spreadsheet, but not visible by default.
我希望它们出现在电子表格中,但默认情况下不可见。
How can I accomplish that? 我该怎么做?
This also did not work: 这也行不通:
hiddenRange.Rows.Hidden = true;
...and this, in fact, caused the app to crash: ...事实上,这导致该应用程序崩溃:
hiddenRange.Hidden = true;
Even these rather sneaky ways of trying to accomplish it did nothing: 甚至这些试图实现目标的偷偷摸摸的方式也无济于事:
//hiddenRange.RowHeight = 0; <= did nothing
hiddenRange.Rows.RowHeight = 0; // <= also does nothing
Yes, you're right, MacroMarc (replying to your comment below); 是的,您说得对,MacroMarc(在下面回复您的评论); this test code does work:
该测试代码可以正常工作:
var testRange = _xlSheet.Range[_xlSheet.Cells[2, 1], _xlSheet.Cells[2, 4]];
testRange.EntireRow.Hidden = true;
...so there's something discombobulated in my brain with regards to my code. ...所以关于我的代码,我的大脑有些混乱。 Maybe it's a timing issue;
也许这是一个时机问题; I'll go over it again, with a fine-toothed comb.
我将用细齿梳再次检查它。
Dicho discombobulatory code is: Dicho组合代码为:
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;
}
...or, stripped of extraneous details: ...或者,去除了多余的细节:
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;
}
It's working now; 现在正在工作; I had to change the row range from a single one to multiple:
我不得不将行范围从单个更改为多个:
if (_hide)
{
var hiddenRange = _xlSheet.Range[_xlSheet.Cells[_curDescriptionTopRow, ITEMDESC_COL], _xlSheet.Cells[_lastRowAdded, TOTALS_COL]];
hiddenRange.EntireRow.Hidden = true;
}
...perhaps it was working as coded before, I just didn't notice it, because what I coded (hiding only one row of every four below the threshold value) was not what I was intending (hiding all four rows below the threshold). ...也许它按以前的方式工作,我只是没有注意到,因为我编码的内容(仅在阈值以下的四分之一隐藏了一行)不是我想要的(隐藏阈值的四行全部) )。
Now the problem is that they (certain rows) are hidden, but I'm not seeing how the user can make those rows visible (which is how the legacy hand-crafted spreadsheet works). 现在的问题是,它们(某些行)是隐藏的,但是我看不到用户如何使这些行可见(这是传统的手工电子表格的工作方式)。
I found out how to do that (manually unhide) here . 我在这里找到了如何做(手动取消隐藏)的方法。 I don't really need to do that myself, I just need to know the user can do it.
我真的不需要自己做,我只需要知道用户可以做到。
If you don't mind using other libraries, ClosedXML is fantastic when working with Excel and free to use. 如果您不介意使用其他库,则在使用Excel并免费使用时,ClosedXML很棒。

Here is an example of how to hide rows in a worksheet: 这是一个如何在工作表中隐藏行的示例:
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");

Would strongly recommend it, it provides lots of useful and nice naming conventions for several functions. 强烈建议您使用它,它为多个函数提供了许多有用且不错的命名约定。 Hope that's of some help!
希望对您有所帮助!
This is how I got it to work, first in a specific way: 这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;
}
...now in a more general/abstract way: ...现在以更一般/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;
}
