如何防止打印左侧 "gutter"（行号）列（EPPlus）？

Question

使用我的 EPPlus 代码创建的电子表格的 "Print Preview" 显示 gutter/row 数字列（可以说是第 0 列）：

如何以编程方式阻止打印 gutter/row 数字 ("crack?") 列？

目前我的打印设置代码如下：

private void ConfigureCustomerSheetForPrinting()
{
    string columnName = GetExcelTextColumnName(customerWorksheet.Dimension.End.Column);
    string printArea = string.Format("A1:{0}{1}", columnName, customerWorksheet.Dimension.End.Row);
    customerWorksheet.PrinterSettings.PrintArea = customerWorksheet.Cells[printArea];
    customerWorksheet.PrinterSettings.FitToPage = true;
    customerWorksheet.PrinterSettings.Orientation = eOrientation.Landscape;
    customerWorksheet.View.ZoomScale = 100;
    customerWorksheet.PrinterSettings.FitToPage = true;
    customerWorksheet.PrinterSettings.FitToHeight = 100;
    customerWorksheet.PrinterSettings.Scale = 100;

    customerWorksheet.PrinterSettings.LeftMargin = (decimal).5 / 2.54M; 
    customerWorksheet.PrinterSettings.RightMargin = (decimal).5 / 2.54M;
    customerWorksheet.PrinterSettings.TopMargin = (decimal).5 / 2.54M;
    customerWorksheet.PrinterSettings.BottomMargin = (decimal).5 / 2.54M;
    customerWorksheet.PrinterSettings.HeaderMargin = (decimal).5 / 2.54M;
    customerWorksheet.PrinterSettings.FooterMargin = (decimal).5 / 2.54M;
}

Answer 1

PrinterSettings 对象中有一个名为 ShowHeaders 的属性，它应该可以满足您的需要。您那里似乎没有它，所以您可能会遗漏它。

customerWorksheet.PrinterSettings.ShowHeaders = false; customerWorksheet.View.ShowHeaders = false;

您可以在 ExcelPrinterSettings class 的 source code 中更明确地看到这一点。

/// <summary>
/// Print headings (column letter and row numbers)
/// </summary>
public bool ShowHeaders
{
    get
    {
        return GetXmlNodeBool(_headersPath, false);
    }
    set
    {
        SetXmlNodeBool(_headersPath, value, false);
    }
}

如果我理解您的要求，您想要显示第 header 列（将 "Row 0" 说成 "A"、"B"、"C" , ...) 但不显示行 headers（比如 "Column 0" 为“1”、“2”3 等）。如果是这样，我从未见过这样做的方法. 根据 DocumentFormat.OpenXml.Spreadsheet.PrintOptions，你可以隐藏 row/col header 或同时显示但不显示 either-or。基本上你和 Richardo 谈论的 ShowHeaders 选项。

我能想到的唯一体面的工作就是用这样的东西来伪造它。这包括将第一行设置为重复。我也将第一行设置为冻结，但这是可选的：

using (var pck = new ExcelPackage(fi))
{
    var wb = pck.Workbook;
    var ws = wb.Worksheets.Add("Sheet1");

    //Make sure headers are not show
    ws.PrinterSettings.ShowHeaders = false;

    //Header
    ws.Cells[1, 1].Value = "A";
    ws.Cells[1, 2].Value = "B";
    ws.Cells[1, 3].Value = "C";
    ws.Cells[1, 4].Value = "D";

    var headerrange = ws.Cells[1, 1, 1, 4];
    headerrange.Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
    headerrange.Style.Border.Top.Style = ExcelBorderStyle.Thin;
    headerrange.Style.Border.Bottom.Style = ExcelBorderStyle.Thin;
    headerrange.Style.Border.Left.Style = ExcelBorderStyle.Thin;
    headerrange.Style.Border.Right.Style = ExcelBorderStyle.Thin;

    ws.View.FreezePanes(1,4);
    ws.PrinterSettings.RepeatRows = new ExcelAddress(":");

    //Some data > 1 page
    for (var i = 0; i < 1000; i++)
    {
        ws.Cells[2 + i, 1].Value = DateTime.Now.AddDays(i);
        ws.Cells[2 + i, 2].Value = i;
        ws.Cells[2 + i, 3].Value = i*100;
        ws.Cells[2 + i, 4].Value = Path.GetRandomFileName();
    }

    //Save it
    pck.Save();
}

这在输出中给出了这个：
