如何防止打印左侧“排水沟”（行号）列（EPPlus）？

Question

使用我的EPPlus代码创建的电子表格的“打印预览”显示了装订线/行号列（可以这么说第0列）：

如何以编程方式防止印刷品中的装订线/行号（“裂缝？”）列？

我的打印设置代码目前如下：

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;
}

如果我理解你的要求，你想要显示列标题（比如说“行0”，“B”，“C”，......），但不显示行标题（说“第0列“为”1“，”2“3”等。如果是这样，我从未见过如何做到这一点。你可以隐藏行/列标题或显示两者但不是 - 或根据DocumentFormat.OpenXml.Spreadsheet.PrintOptions。基本上是您和Richardo谈到的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("$1:$1");

    //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();
}

在输出中给出了这个：

这在打印预览中（我向下滚动了几页）：

PrinterSettings对象中有一个名为public class CustomAdapter extends BaseAdapter { private ArrayList songList; private LayoutInflater layoutInflater; public boolean isVisible; public CustomAdapter(Context context, ArrayList songList){ this.songList = songList; layoutInflater = LayoutInflater.from(context); } public boolean isVisible(){ return isVisible; } public void setIsVisible(boolean isVisible){ this.isVisible = isVisible; } @Override public int getCount() { return songList.size(); } @Override public Object getItem(int position) { return songList.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { final ViewHolder holder; if (convertView == null){ convertView = layoutInflater.inflate(R.layout.layout_list_row, null); holder = new ViewHolder(); holder.backgroundImage = (ImageView) convertView.findViewById(R.id.backgroundImage); holder.topText = (TextView) convertView.findViewById(R.id.topText); holder.bottomText = (TextView) convertView.findViewById(R.id.bottomText); holder.button_repeat = (ImageButton) convertView.findViewById(R.id.button_repeat); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } SongItem songItem = (SongItem) songList.get(position); holder.topText.setText(songItem.getTopText()); holder.bottomText.setText(songItem.getBottomText()); holder.backgroundImage.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (holder.button_repeat.getVisibility() == View.VISIBLE) holder.button_repeat.setVisibility(View.GONE); else holder.button_repeat.setVisibility(View.VISIBLE); } }); return convertView; } static class ViewHolder { ImageView backgroundImage; TextView topText; TextView bottomText; ImageButton button_repeat; } } 的属性，可以满足您的需要。你似乎没有它，所以你可能会错过它。

ShowHeaders customerWorksheet.PrinterSettings.ShowHeaders = false;

您可以在customerWorksheet.View.ShowHeaders = false;类的source code中更明确地看到这一点。
