Question

我已经获得了这段代码，该代码应该左对齐特定列的内容：

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);

它有效......有时候：

为什么有时会发生右对齐？

任何可以被视为int（不包含alpha字符或破折号）右对齐的值;但是为什么它不尊重明确的左对齐，无论它是否看起来像＆＃34;一个int？

有一些＆＃34;一般＆＃34;在所有特定于列的代码之后应用于整行的格式：

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);

......但这不应影响对齐。

在上面第一个显示的代码作为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);
    }
}

...它是硼化的，配置用于打印，最后将工作表写入磁盘：

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);

我无法想象更改版画或打印配置会更改工作表上特定列的对齐方式，但以防万一可能，以下是这些方法：

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 = "$1:$1";
    customerWorksheet.PageSetup.PrintTitleRows = repeatableRowRange;
}

这怎么会导致列对齐不尊重，不服从和忽略clear和present指令左对齐其内容？

更新

根据我对答案的理解，我改变了这个：

rowRange.SetStyle(style4);

......对此：

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。

这是显式设置问题列的代码：

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);

所以我这里没有使用Range，而是一个单元格。我应该使用范围，以便我可以使用ApplyStyle（）？我尝试过这样做，但它似乎并不想接受PutValue（）等。

此外，提供的值（frbdbc.MemberItemCode）是一个字符串，所以不应该这样可以防止Excel像对待它一样对待它吗？我还必须做些什么让Excel知道，＆＃34;嘿，这是一个字符串，只是按原样显示。＆＃34;

我尝试了Aspose发送给我的这段代码：

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 });

......它仍然没有区别。

我认为这可行，我发现here：

micStyle.NumberFormat = 2;

（替换＆＃34; 2＆＃34;用任何数字的代理人替换＃34;文字＆＃34;）;但是＆＃34; NumberFormat＆＃34;不被承认。这是一个过时的例子吗？

好的，必须有一些合乎逻辑的理由说明为什么会发生这种情况。以下是我对该列进行的操作：

首先，写入标题行：

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);

    . . .
}

所以我在标题行上对齐列;它是索引4，IOW列＆＃34; E＆＃34;

接下来，多次调用AddCustomerRow（），填充＆＃34;数据＆＃34;工作表的一部分（标题行下面的所有内容）：

    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 });
    }

此处，对齐也设置为左侧。在设置每一列之后，一个＆＃34;通用行样式＆＃34;创建，有条件地为整行着色。这很好 - 适当的行被着色。

然后，因为标题行的着色不像之前尝试的那样起作用（将其设置为LightBlue不起作用），所以我会在面部之后这样做：

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);
}

...边框也会添加到该行。最后，边框被添加到数据行（第1行的所有内容）：

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);
}

然后将文件保存到磁盘 - 将MemberItemCode列中的某些项目混合为左对齐，其他项目右对齐。为什么没有像我这样的电话：

Column[3].Alignment = AlignLeft;

...可以根据需要轻松对齐特定列中的所有内容;还是有吗？因为我尝试的任何一种都不起作用或者非常有气质，所以这样的东西肯定会很方便。

Answer 1

我认为上述问题是由于您使用从头创建的对象覆盖样式的所有方面而引起的。请注意，将样式应用于单元格时，首先会从该单元格中获取样式，这样可以保留应用于该单元格的数字格式。但是，当您从头开始创建Style对象并在使用Range.SetStyle时将样式应用于范围时，新创建的Style对象的每个方面都会覆盖到该范围，这会导致每个单元格的格式更改为General。范围。我建议您使用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对象的方面。

注意：我在Aspose担任开发人员传播者。

Answer 2

我能让这个工作的唯一方法就是“通过明确地将该列中的所有单元格设置为在完成其他所有操作后左对齐”来“强制执行”：

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);
    }
}

为什么单元格内容设置为左对齐有时对齐（Aspose Cells）？
