如何使用 EPPlus C# 在单个单元格中直观地显示多行文本

Question

我目前正在使用大量数据为我的工作场所创建和显示视觉上令人愉悦的文档，其中显示运动/体育数据列表。

我有一个栏目，用于显示这些运动的频道。然而，有些运动有多个频道，我决定将它们放在运动名称和运动时间旁边的同一个单元格中。所附图片应显示我得到的与我想要的。

我不会提供我的所有代码，因为它很草率，而且过多。然而，下面的代码块中的概念应该足够了

// Create a new worksheet
var worksheet = package.Workbook.Worksheets.Add($"{DateTimeString} Lineup");

// Change all cells to font Calibri 24px
worksheet.Cells.Style.Font.Name = "Calibri";
worksheet.Cells.Style.Font.Size = 24;

// Merge cells A1:C1
worksheet.Cells["A1:C1"].Merge = true;
worksheet.Cells["A1:C1"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
worksheet.Cells["A1:C1"].Style.Font.Bold = true;
worksheet.Cells["A1:C1"].Style.Font.UnderLine = true;
worksheet.Cells["A1:C1"].Style.Border.BorderAround(ExcelBorderStyle.Thin);


// Set A1:C1 to "Sunday NFL Games"
worksheet.Cells["A1"].Value = $"{dayOfWeek} {League.LeagueNameShort} Games";

// Set A2 to "Time", B2 to "Channel", and C2 to "Games" + DateTime.Now.ToString("MM/dd/yyyy")
worksheet.Cells["A2"].Value = "Time";
worksheet.Cells["A2"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
worksheet.Cells["A2"].Style.Font.Bold = true;
worksheet.Cells["A2"].Style.Border.BorderAround(ExcelBorderStyle.Thin);
worksheet.Cells["B2"].Value = "Channel";
worksheet.Cells["B2"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
worksheet.Cells["B2"].Style.Font.Bold = true;
worksheet.Cells["B2"].Style.Border.BorderAround(ExcelBorderStyle.Thin);
worksheet.Cells["C2"].Value = "Games " + date.ToString("MM/dd/yyyy");
worksheet.Cells["C2"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
worksheet.Cells["C2"].Style.Font.Bold = true;
worksheet.Cells["C2"].Style.Border.BorderAround(ExcelBorderStyle.Thin);

//Find Games
int row = 3;

foreach (SportDataExport ex in GetSportDataExport(DateTimeString, League).OrderBy(export => DateTime.ParseExact(export.GameTime, "h:mmtt", CultureInfo.InvariantCulture)))
{
    //Set Cell Values
    worksheet.Cells[row, 1].Value = ex.GameTime;
    worksheet.Cells[row, 2].Value = ex.Channels;
    worksheet.Cells[row, 3].Value = ex.Teams;

    if(ex.ChannelCount == 0)
    {
        worksheet.Row(row).Height = 31.5;
    }
    else
    {
        worksheet.Row(row).Height = 31.5 * ex.ChannelCount;
    }

    //Style Cells
    worksheet.Cells[row, 1].Style.VerticalAlignment = ExcelVerticalAlignment.Center;
    worksheet.Cells[row, 2].Style.VerticalAlignment = ExcelVerticalAlignment.Center;
    worksheet.Cells[row, 3].Style.VerticalAlignment = ExcelVerticalAlignment.Center;
    worksheet.Cells[row, 1].Style.Border.BorderAround(ExcelBorderStyle.Thin);
    worksheet.Cells[row, 2].Style.Border.BorderAround(ExcelBorderStyle.Thin);
    worksheet.Cells[row, 3].Style.Border.BorderAround(ExcelBorderStyle.Thin);

    row = row + 1;
}

AutoSizeWorksheet(worksheet);
// Save the Excel package
FileInfo fileInfo = new FileInfo(filePath);
package.SaveAs(fileInfo);

我尝试过手动设置行高、设置“WordWrap”和3种不同的换行方法。一旦用户打开 Excel 工作表，单击“进入单元格”并按 Enter 键或通过选择另一个单元格退出单元格，该单元格就会被固定。

Answer 1

需要将所需列的

WrapText

属性设置为

true

：

worksheet.Cells["B2"].Value.WrapText= true;

然后您可以使用

Environment.NewLine

将文本换行。
