为什么设置为左对齐的单元格内容有时会右对齐（Aspose Cells）？

Question

我有这段代码，它应该 left-align 特定列的内容：

Cell memberItemCodeCell = customerWorksheet.Cells[rowToPopulate, MEMBERITEMCODE_COL];
memberItemCodeCell.PutValue(frbdbc.MemberItemCode, true);
var micStyle = memberItemCodeCell.GetStyle();
micStyle.Font.Name = fontForSheets;
micStyle.Font.Size = 11;
micStyle.HorizontalAlignment = TextAlignmentType.Left;
micStyle.IsTextWrapped = false;
memberItemCodeCell.SetStyle(micStyle, flag);

有效...有时：

为什么 right-aligning 有时会发生？

任何可以被视为 int 的值（不包含字母字符或破折号）right-aligns；但为什么它不尊重显式 left-aligning，不管它 "looked like" 是不是一个 int?

在所有 column-specific 代码之后，有一些 "general" 格式适用于整行：

CellsFactory cf = new CellsFactory();
Style style4 = cf.CreateStyle();
if (shipVarDbl >= 1.0) // fewer were shipped than were ordered
{
    style4.ForegroundColor = Color.LightGreen;
}
else if (shipVarDbl < 0.0) // more were shipped than were ordered
{
    style4.ForegroundColor = Color.PaleVioletRed;
}
style4.Font.Name = fontForSheets;
style4.Font.Size = 11;
style4.Pattern = BackgroundType.Solid;
rowRange.SetStyle(style4);

...但这不应该影响对齐。

在上面首先显示的代码作为 PopulateCustomerSheet() 方法的一部分运行之后：

private void PopulateCustomerSheet()
{
    try
    {
        if (null == _fillRateByDistributorByCustomerList) return;
        foreach (FillRateByDistributorByCustomer frbdbc in _fillRateByDistributorByCustomerList)
        {
            AddCustomerRow(frbdbc);
        }
        AutoFitterOptions options = new AutoFitterOptions { OnlyAuto = true };
        customerWorksheet.AutoFitColumns(options);
    }
    catch (Exception ex)
    {
        RoboReporterConstsAndUtils.HandleException(ex);
    }
}

...已加边框，为打印配置，最后将 sheet 写入磁盘：

BorderizeDataPortionOfCustomerSheet(); 
ConfigureCustomerSheetForPrinting();

// Write the file to disk
string fromAsYYYYMMDD = DateTime.Now.ToString("yyyy-MM-dd_hh-mm-ss");
RoboReporterConstsAndUtils.SetUniqueFolder(_unit);
String _uniqueFolder = RoboReporterConstsAndUtils.uniqueFolder;

var sharedFolder = String.Format(@"\storageblade\cs\REPORTING\RoboReporter\{0}", _uniqueFolder);
RoboReporterConstsAndUtils.ConditionallyCreateDirectory(sharedFolder);

var filename = String.Format(@"{0}\{1} - Fill Rate - {2}.xlsx", sharedFolder, _unit, fromAsYYYYMMDD);
if (File.Exists(filename))
{
    File.Delete(filename);
}
workBook.Save(filename, SaveFormat.Xlsx);

我无法想象边框化或打印配置会更改 sheet 上特定列的对齐方式，但为了以防万一，这些方法如下：

private void BorderizeDataPortionOfCustomerSheet()
{
    int rowsUsed = customerWorksheet.Cells.Rows.Count;
    int colsUsed = SHIPVARIANCE_COL;

    string bottomRightRange = string.Format("P{0}", rowsUsed);
    var range = customerWorksheet.Cells.CreateRange("A1", bottomRightRange);

    //Setting border for each cell in the range
    var style = workBook.CreateStyle();
    style.SetBorder(BorderType.BottomBorder, CellBorderType.Thin, Color.Black);
    style.SetBorder(BorderType.LeftBorder, CellBorderType.Thin, Color.Black);
    style.SetBorder(BorderType.RightBorder, CellBorderType.Thin, Color.Black);
    style.SetBorder(BorderType.TopBorder, CellBorderType.Thin, Color.Black);

    for (int r = range.FirstRow; r < range.RowCount; r++)
    {
        for (int c = range.FirstColumn; c < range.ColumnCount; c++)
        {
            Cell cell = customerWorksheet.Cells[r, c];
            cell.SetStyle(style, new StyleFlag()
            {
                TopBorder = true,
                BottomBorder = true,
                LeftBorder = true,
                RightBorder = true
            });
        }
    }

    //Setting outline border to range
    range.SetOutlineBorder(BorderType.TopBorder, CellBorderType.Thin, Color.Black);
    range.SetOutlineBorder(BorderType.BottomBorder, CellBorderType.Thin, Color.Black);
    range.SetOutlineBorder(BorderType.LeftBorder, CellBorderType.Thin, Color.Black);
    range.SetOutlineBorder(BorderType.RightBorder, CellBorderType.Thin, Color.Black);

    customerWorksheet.FreezePanes(FIRST_DATA_ROW, SHORTNAME_COL, rowsUsed, colsUsed);
}

private void ConfigureCustomerSheetForPrinting()
{
    const double INCHES_TO_CENTIMETERS_FACTOR = 2.54;
    string lastColumn = GetExcelTextColumnName(customerWorksheet.Cells.Columns.Count);
    string printArea = String.Format("A1:{0}{1}", lastColumn, customerWorksheet.Cells.Rows.Count);
    customerWorksheet.PageSetup.PrintArea = printArea;
    customerWorksheet.PageSetup.Orientation = PageOrientationType.Landscape;

    // I don't know if this does anything; I would like to set it to 54%...
    customerWorksheet.PageSetup.IsPercentScale = true;

    customerWorksheet.PageSetup.FitToPagesWide = 1;
    customerWorksheet.PageSetup.FitToPagesTall = 0;

    customerWorksheet.PageSetup.LeftMargin = 0.5 * INCHES_TO_CENTIMETERS_FACTOR;
    customerWorksheet.PageSetup.RightMargin = 0.5 * INCHES_TO_CENTIMETERS_FACTOR;
    customerWorksheet.PageSetup.TopMargin = 0.5 * INCHES_TO_CENTIMETERS_FACTOR;
    customerWorksheet.PageSetup.BottomMargin = 0.5 * INCHES_TO_CENTIMETERS_FACTOR;
    customerWorksheet.PageSetup.HeaderMargin = 0;
    customerWorksheet.PageSetup.FooterMargin = 0;

    // Repeat rows
    string repeatableRowRange = ":";
    customerWorksheet.PageSetup.PrintTitleRows = repeatableRowRange;
}

这怎么会导致列对齐不尊重、违背和忽略对 left-align 其内容的清晰和当前指令？

更新

根据我对答案的理解，我改变了这个：

rowRange.SetStyle(style4);

...为此：

var flag = new StyleFlag
{
    CellShading = true,
    FontName = true,
    FontSize = true,
    FontColor = true,
    FontBold = true,
    NumberFormat = true
};

rowRange.ApplyStyle(style4, flag);

...但没有任何区别。

这是明确设置问题列的代码：

Cell memberItemCodeCell = customerWorksheet.Cells[rowToPopulate, MEMBERITEMCODE_COL];
memberItemCodeCell.PutValue(frbdbc.MemberItemCode, true);
var micStyle = memberItemCodeCell.GetStyle();
micStyle.Font.Name = fontForSheets;
micStyle.Font.Size = 11;
micStyle.HorizontalAlignment = TextAlignmentType.Left;
micStyle.IsTextWrapped = false;
memberItemCodeCell.SetStyle(micStyle, flag);

所以我在这里没有使用范围，而是使用了单元格。我应该使用一个范围，以便我可以使用 ApplyStyle() 吗？我尝试这样做，但它似乎不想接受 PutValue() 等

此外，提供的值 (frbdbc.MemberItemCode) 是一个字符串，所以这不应该阻止 Excel 将其视为 int 吗？我还必须做些什么才能让 Excel 知道，"Hey, this is a string, just present it as-is."

我尝试了 Aspose 发给我的代码：

customerWorksheet.Cells.CreateRange(rangeBegin, rangeEnd).ApplyStyle(style4, new StyleFlag() { Font = true, CellShading = true });

在上下文中：

string rangeBegin = RoboReporterConstsAndUtils.GetRangeLettersNumbersAsStr(SHORTNAME_COL + 1, rowToPopulate);
string rangeEnd = RoboReporterConstsAndUtils.GetRangeLettersNumbersAsStr(SHIPVARIANCE_COL + 1, rowToPopulate);

CellsFactory cf = new CellsFactory();
Style style4 = cf.CreateStyle();
if (shipVarDbl >= 1.0) // fewer were shipped than were ordered
{
    style4.ForegroundColor = Color.LightGreen;
}
else if (shipVarDbl < 0.0) // more were shipped than were ordered
{
    style4.ForegroundColor = Color.PaleVioletRed;
}
style4.Font.Name = fontForSheets;
style4.Font.Size = 11;
style4.Pattern = BackgroundType.Solid;
customerWorksheet.Cells.CreateRange(rangeBegin, rangeEnd).ApplyStyle(style4, new StyleFlag() { Font = true, CellShading = true });

...仍然没有区别。

我认为这可能有效，我发现了 here:

micStyle.NumberFormat = 2;

（用代表 "Text" 的任何数字替换“2”）；但无法识别 "NumberFormat"。这是一个过时的例子吗？

好吧，一定有一些合乎逻辑的原因，为什么这[没有]发生。以下是我对该列所做的操作，顺序为：

首先，header行写成：

private static readonly int MEMBERITEMCODE_COL = 4;
. . .
private void AddCustomerSheetHeaderRow()
{
    var flag = new StyleFlag
    {
        CellShading = true,
        FontName = true,
        FontSize = true,
        FontColor = true,
        FontBold = true,
        NumberFormat = true
    };

    . . .

    CellsFactory cfMemberItemCode = new CellsFactory();
    Cell MemberItemCodeCell = customerWorksheet.Cells[0, MEMBERITEMCODE_COL];
    MemberItemCodeCell.PutValue("Member Item Code");
    var styleMemberItemCode = cfMemberItemCode.CreateStyle();
    styleMemberItemCode.HorizontalAlignment = TextAlignmentType.Left;
    styleMemberItemCode.Font.Name = fontForSheets;
    styleMemberItemCode.Font.IsBold = true;
    styleMemberItemCode.Font.Size = 11;
    styleMemberItemCode.ForegroundColor = Color.LightBlue;
    styleMemberItemCode.Pattern = BackgroundType.Solid;
    MemberItemCodeCell.SetStyle(styleMemberItemCode, flag);

    . . .
}

所以我将列对齐到 header 行；它是索引 4，IOW 列 "E"

接下来，多次调用 AddCustomerRow()，填充 sheet 的 "data" 部分（header 行下方的所有内容）：

    private void AddCustomerRow(FillRateByDistributorByCustomer frbdbc) 
    {
        var flag = new StyleFlag
        {
            CellShading = true,
            FontName = true,
            FontSize = true,
            FontColor = true,
            FontBold = true,
            NumberFormat = true
        };

        . . .

        // This is sometimes seen as an int by Excel, and sports the green warning triangle
        // Fixed that with the second (true) arg to PutValue(), but it right-aligns int-like vals...?!@?
        Cell memberItemCodeCell = customerWorksheet.Cells[rowToPopulate, MEMBERITEMCODE_COL];
        memberItemCodeCell.PutValue(frbdbc.MemberItemCode, true);
        var micStyle = memberItemCodeCell.GetStyle();
        micStyle.Font.Name = fontForSheets;
        micStyle.Font.Size = 11;
        micStyle.HorizontalAlignment = TextAlignmentType.Left;
        micStyle.IsTextWrapped = false;
        memberItemCodeCell.SetStyle(micStyle, flag);

        . . .

        string rangeBegin = RoboReporterConstsAndUtils.GetRangeLettersNumbersAsStr(SHORTNAME_COL + 1, rowToPopulate);
        string rangeEnd = RoboReporterConstsAndUtils.GetRangeLettersNumbersAsStr(SHIPVARIANCE_COL + 1, rowToPopulate);

        CellsFactory cf = new CellsFactory();
        Style style4 = cf.CreateStyle();
        if (shipVarDbl >= 1.0) // fewer were shipped than were ordered
        {
            style4.ForegroundColor = Color.LightGreen;
        }
        else if (shipVarDbl < 0.0) // more were shipped than were ordered
        {
            style4.ForegroundColor = Color.PaleVioletRed;
        }
        style4.Pattern = BackgroundType.Solid;
        style4.Font.Name = fontForSheets;
        style4.Font.Size = 11;
        customerWorksheet.Cells.CreateRange(rangeBegin
|rangeEnd).ApplyStyle(style4, new StyleFlag() { Font = true,
CellShading = true });
    }

在这里，对齐方式也设置为左对齐。设置每一列后，将创建一个 "general purpose row style"，以有条件地为整行着色。效果很好 - 相应的行已着色。

然后，因为 header 行的着色没有像以前尝试的那样起作用（将其设置为浅蓝色不起作用），所以我在面部之后这样做：

private void RecolorizeTopRowOfCustomerSheet()
{
    . . .

    CellsFactory cfMemberItemCode = new CellsFactory();
    Cell MemberItemCodeCell = customerWorksheet.Cells[0,
MEMBERITEMCODE_COL];
    var styleMemberItemCode = cfMemberItemCode.CreateStyle();
    styleMemberItemCode.HorizontalAlignment = TextAlignmentType.Left;
    styleMemberItemCode.Font.Name = fontForSheets;
    styleMemberItemCode.Font.IsBold = true;
    styleMemberItemCode.Font.Size = 11;
    styleMemberItemCode.ForegroundColor = Color.LightBlue;
    styleMemberItemCode.Pattern = BackgroundType.Solid;
    MemberItemCodeCell.SetStyle(styleMemberItemCode);

    . . .

    // Give it borders
    Range _range;
    _range = customerWorksheet.Cells.CreateRange("A1", "P1");
    //Set the borders with hair lines style.
    _range.SetOutlineBorders(CellBorderType.Hair, Color.Black);
}

...边框也添加到该行。最后，将边框添加到数据行（第 1 行之后的所有内容）：

private void BorderizeDataPortionOfCustomerSheet()
{
    int rowsUsed = customerWorksheet.Cells.Rows.Count;
    int colsUsed = SHIPVARIANCE_COL;

    string bottomRightRange = string.Format("P{0}", rowsUsed);
    var range = customerWorksheet.Cells.CreateRange("A1", bottomRightRange);

    //Setting border for each cell in the range
    var style = workBook.CreateStyle();
    style.SetBorder(BorderType.BottomBorder, CellBorderType.Thin, Color.Black);
    style.SetBorder(BorderType.LeftBorder, CellBorderType.Thin, Color.Black);
    style.SetBorder(BorderType.RightBorder, CellBorderType.Thin, Color.Black);
    style.SetBorder(BorderType.TopBorder, CellBorderType.Thin, Color.Black);

    for (int r = range.FirstRow; r < range.RowCount; r++)
    {
        for (int c = range.FirstColumn; c < range.ColumnCount; c++)
        {
            Cell cell = customerWorksheet.Cells[r, c];
            cell.SetStyle(style, new StyleFlag()
            {
                TopBorder = true,
                BottomBorder = true,
                LeftBorder = true,
                RightBorder = true
            });
        }
    }

    //Setting outline border to range
    range.SetOutlineBorder(BorderType.TopBorder, CellBorderType.Thin, Color.Black);
    range.SetOutlineBorder(BorderType.BottomBorder, CellBorderType.Thin, Color.Black);
    range.SetOutlineBorder(BorderType.LeftBorder, CellBorderType.Thin, Color.Black);
    range.SetOutlineBorder(BorderType.RightBorder, CellBorderType.Thin, Color.Black);

    customerWorksheet.FreezePanes(FIRST_DATA_ROW, SHORTNAME_COL, rowsUsed, colsUsed);
}

然后文件被保存到磁盘 - 混杂了 MemberItemCode 列 left-aligned 和其他 right-aligned 中的一些项目。为什么没有像这样的电话：

Column[3].Alignment = AlignLeft;

...这将很容易地根据需要对齐特定列中的所有内容；还是有？由于我正在尝试的方法要么不起作用，要么非常喜怒无常，因此类似的东西肯定会派上用场。

Answer 1

我认为造成上述问题的原因是您用从头开始创建的对象覆盖了样式的所有方面。请注意，当您将样式应用到单元格时，您首先从该单元格获取样式，这允许您保留应用于它的数字格式。但是，当您从头开始创建 Style 对象并在使用 Range.SetStyle 时将样式应用于某个范围时，新创建的 Style 对象的每个方面都会被覆盖到该范围，这会导致每个方面的格式更改为 General范围内的单元格。我建议您改用 Range.ApplyStyle 方法，它允许您将 StyleFlag 的实例传递给上述方法。这样，您可以控制要覆盖的 Style 对象的各个方面。

注意：我在 Aspose 担任开发人员布道师。

Answer 2

我能让它工作的唯一方法是 "brute force it" 在完成其他所有操作后将该列中的所有单元格显式设置为 left-aligned：

private static readonly int MEMBERITEMCODE_COL = 4;
. . .
SetAllCustomerSheetColValsLeftAligned(MEMBERITEMCODE_COL);
BorderizeDataPortionOfCustomerSheet();    
. . .    
private void SetAllCustomerSheetColValsLeftAligned(int colIndex)
{
    int rowsUsed = customerWorksheet.Cells.Rows.Count;
    CellsFactory cf = new CellsFactory();
    Cell currentCell = null;
    Style currentStyle = null;
    for (int i = 2; i <= rowsUsed; i++)
    {
        currentCell = customerWorksheet.Cells[i, colIndex];
        currentStyle = cf.CreateStyle();
        currentStyle.HorizontalAlignment = TextAlignmentType.Left;
        currentStyle.Font.Name = fontForSheets;
        currentStyle.Font.Size = 11;
        currentCell.SetStyle(currentStyle);
    }
}

为什么设置为左对齐的单元格内容有时会右对齐（Aspose Cells）？

Why would cell contents set to align left sometimes align right (Aspose Cells)?
