如何使用 OpenXml 使单元格中的某些文本变为粗体

Question

我已经尝试使用加粗的特定文本

 Bold fbld = new Bold();

但它会使大厅单元格变粗。

在上图中，单元格中有一些粗体文本。

如何在 OpenXml 中使用 C# 做到这一点？

Answer 1

您需要为不同样式的文本使用单独的Run 元素。您可以通过创建 RunProperties 元素并向其中添加 Bold 元素来添加粗体。

以下代码适用于没有行的现有电子表格（请注意，我没有添加用于合并的代码，因为这只会增加复杂性 - 如果您需要帮助，请参阅 my answer here）

using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(filename, true))
{
    WorkbookPart workBookPart = spreadsheetDocument.WorkbookPart;

    WorkbookPart workbookPart = spreadsheetDocument.WorkbookPart;
    WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();
    SheetData sheetData = worksheetPart.Worksheet.Elements<SheetData>().First();

    //create a row
    Row row1 = new Row() { RowIndex = 1U };

    //create a new inline string cell
    Cell cell = new Cell() { CellReference = "A1" };
    cell.DataType = CellValues.InlineString;

    //create a run for the bold text
    Run run1 = new Run();
    run1.Append(new Text("ABC"));
    //create runproperties and append a "Bold" to them
    RunProperties run1Properties = new RunProperties();
    run1Properties.Append(new Bold());
    //set the first runs RunProperties to the RunProperties containing the bold
    run1.RunProperties = run1Properties;

    //create a second run for the non-bod text
    Run run2 = new Run();
    run2.Append(new Text(Environment.NewLine + "XYZ") { Space = SpaceProcessingModeValues.Preserve });

    //create a new inline string and append both runs
    InlineString inlineString = new InlineString();
    inlineString.Append(run1);
    inlineString.Append(run2);

    //append the inlineString to the cell.
    cell.Append(inlineString);

    //append the cell to the row
    row1.Append(cell);

    sheetData.Append(row1);
}
